mg_disk: fix enum REQ_OP_ kbuild error
Because we define WRITE/READ as REQ_OPs, we cannot do switch (rq_data_dir(request)) case READ .... case WRITE ... without getting warnings about handling other REQ_OPs. This just has mq_disk do a if/else like it does in other places. Signed-off-by: Mike Christie <mchristi@redhat.com> Signed-off-by: Jens Axboe <axboe@fb.com>
