msm: camera: Fix ispif stop frame boundary timeout issue

Previously a 500ms timeout set for stop frame boundary.
But sometimes when doing snapshot with large linecount may make
the frame rate drop to 1fps. Set the timeout to 1s to avoid camera
crash.

msm: camera2: Validate frame during timeout in cpp driver

During long stability stress runs, invalid frames are encountered
in timeout processing. When frame acknowledgement is delayed by
firmware due to various reasons the timeout handler could hit
frame that are already processed. Hence adding NULL condition
check to avoid invalid frame access.
