bdev/xnvme: enable polling on io_uring_cmd 



Fixes #2708 for io_uring_cmd.

This is a minimal approach to enabling polling for bdev_xnvme. Ideally,
more would be done, however, there are several blockers to remove when
doing so. Thus, this commit only enables polling on
io_mechanism=io_uring_cmd.
