msm: cvp: convert infinite wait to timeout wait

CVP driver waits indefinitely for response callback.
This wait is done after acquiring a lock used by
other threads in video driver. As a result, during
device power suspend, the kernel suspend thread, which
is waiting on above lock, waits and leads to hung.
