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.
