videobuf2-core: Check user space planes array in dqbuf
commit e7e0c3e26587749b62d17b9dd0532874186c77f7 upstream.
The number of planes in videobuf2 is specific to a buffer. In order to
verify that the planes array provided by the user is long enough, a new
vb2_buf_op is required.
Call __verify_planes_array() when the dequeued buffer is known. Return an
error to the caller if there was one, otherwise remove the buffer from the
done list.
