Hans Verkuil 9015fcc256 media: videobuf2-core: sanity checks for requests and qbuf
The combination of supports_requests == 1 and min_buffers_needed > 0
is not allowed, WARN on that and return an error.

Also check that if vb2_core_qbuf() is called from req_queue, that it
doesn't return an error, unless it is -EIO.
