sched: Fix reference to stale task_struct in try_to_wake_up()

try_to_wake_up() currently drops p->pi_lock and later checks for need
to notify cpufreq governor on task migrations or wakeups. However the
woken task could exit between the time p->pi_lock is released and the
time the test for notification is run. As a result, the test for
notification could refer to an exited task. task_notify_on_migrate(p)
could thus lead to invalid memory reference.

Fix this by running the test for notification with task's pi_lock
held.

qseecom: Just check current bus scaling mode in qseecom_suspend

In current qseecom_suspend function, qseecom will scale down bus
bandwidth if both of accumultive mode and current mode are not
INACTIVE. But if device goes into suspend before bus scaling timeout
happens, the accumulative mode may be zero but current mode is
still not INACTIVE. This may prevent the device going to suspend,
thus, make a change to just check current bus scaling mode in
qseecom_suspend.

even if keymaster app doesn't need to be unloaded from TZ, so as to
avoid memory leak.

msm: kgsl: Ignore signals for ringbuffer timestamp waits

Ignore signals when waiting for ringbuffer timestamp since
the wait needs to complete regardless of whether the process
got a signal. Also, increase the wait timeout for context
detachment to 30s instead of 10s. Large IB's can take longer
than 10s to retire and if a hang happens then recovering from
the hang and completing the long IB's will take much longer
than 10s, bump this timer to 30s which should be sufficient
for the context's commands to retire even if hang happens.

msm: vidc: Handle hfi session creation failures properly

Previously, when the hfi session creation failed, the hfi session was
left intact.  So, in case of timeouts, if the core responded beyond the
time out, the driver would handle the message thinking that it's a valid
session.  This commit cleans up the hfi session in case session_init
fails (or times out).

Also rename msm_comm_recover_from_session_error to msm_comm_kill_session,
as the latter was a misnomer, as the function was used to abort a session.

msm: vidc: Handle max clients error from video hardware

Use instance "lock" instead of "sync_lock" variable for
mutex lock/unlock for video instance state change operation
else session init will be timed out due to dead lock when
max clients error is received from video hardware because
"sync_lock" is already acquired before session init.
At the same time do not free the session when any error
is received from video hardware, if freed results in
dangling pointer access when video driver wants to send
any commands to video hardware after session error,
leading to device reset. The proper way of session cleanup
is already being done upon receiving any errors from
video hardware.
