sched: Remove redundant update_runtime notifier

migration_call() will do all the things that update_runtime() does.
So let's remove it.

Furthermore, there is potential risk that the current code will catch
BUG_ON at line 689 of rt.c when do cpu hotplug while there are realtime
threads running because of enabling runtime twice while the rt_runtime
may already changed.

sched: Fix hotplug vs. set_cpus_allowed_ptr()

Lai found that:

  WARNING: CPU: 1 PID: 13 at arch/x86/kernel/smp.c:124 native_smp_send_reschedule+0x2d/0x4b()
  ...
  migration_cpu_stop+0x1d/0x22

was caused by set_cpus_allowed_ptr() assuming that cpu_active_mask is
always a sub-set of cpu_online_mask.

This isn't true since 5fbd036b552f ("sched: Cleanup cpu_active madness").

So set active and online at the same time to avoid this particular
problem.

mmc: block: Fix an invalid use of req->cmd_flag in DISCARD operation

When handling a DISCARD operation, the MMC request data structure may be
freed in memory. Therefore, it can't be used to retrieve the cmd_flags
for checking if MMC_REQ_NOREINSERT_MASK is set:
(!(mq->mqrq_cur->req->cmd_flags & MMC_REQ_NOREINSERT_MASK)))).

To prevent the issue we should use the local variable of cmd_flags.
