msm: camera: check buffer validity in isp buf mgr

When someone asks for buffer from isp_buf_mgr, check
if buffer is valid. This is done by verifying if it is
present in the list of buffers for this session.

This will potentially avoid few kinds of page faults.

msm: camera: Add defensive check in ISPIF driver

In case of error handling, call ispif release only if ispif handle
is valid. In case of mm-qcamara-daemon crash when camera is not open,
these handles are not valid. Hence it leads to kernel crash in ispif
release handler.

msm-camera: Dividing unified buffer in proportion to the image size

Write masters writing large images require large latency buffers in
unified buffer whereas write masters writing smaller images don't,
Allocating latency buffer in proportion to image size will reduce
buf overflows

msm: camera: exit camera incase axi gets timeout

AXI hits timeout while stopping due to sensor not streaming.
Simply returning error from here puts AXI and camif in still
running state whereas userspace proceeds with releasing the
buffers. This fix ensures we halt AXi and stop camif in sensor
not streaming case. Thus avoid page faults and a delay in
stopping camera.

msm: camera: Fix crash in ispif release

There is a BUG_ON in ispif release function for
ispif base address. but in case of just open and close
of ispif subdevice leads to ispif base NULL.

BUG_ON is removed and proper error is added in ispif
release function to fix the issue.

msm: camera: Fix possible NULL pointer dereference.

The result of memory allocation in msm_isp_get_buf is not checked for
success before use. This can lead to NULL pointer dereference.
