msm: camera: Make ISP and camera driver not interruptible

Change wait_event_interruptible_timeout to wait_completion_timeout
and change wait_completion_timeout_interruptible to
wait_event_timeout to avoid keeping on getting signaled
which may cause infinite loop when camera daemon fails
to put events back.
