mm-video-v4l2: Protect buffer access and increase input buffer size
Protect buffer access for below scenarios:
*Increase the scope of buf_lock in free_buffer to avoid access
of freed buffer for both input and output buffers. Also, add check
before output buffer access.
*Disallow allocate buffer mode after client has called use buffer.
Allocate additional 512 bytes of memory for input buffers on top of
allocation size as per hardware requirement.
