media: raspberrypi: cfe: Fix min_reqbufs_allocation
The driver checks if "vq->max_num_buffers + *nbuffers < 3", but
vq->max_num_buffers is (by default) 32, so the check is never true. Nor
does the check make sense.
The original code in the BSP kernel was "vq->num_buffers + *nbuffers <
3", but got mangled along the way to upstream. The intention was to make
sure that at least 3 buffers are allocated.
Fix this by removing the bad lines and setting q->min_reqbufs_allocation
to three.
