Daniel Verkamp 02ccb0f791 bdev: make check_io callback optional ...

If a bdev doesn't need to be polled, allow it to specify NULL for the
check_io function pointer to indicate that no poller needs to be
registered.

This will be useful for virtual blockdevs that don't have any associated
hardware to poll.
