Subject: [PATCH blktests v2 03/11] common/xfs: Create common helper to verify block device with xfs

Make a common helper from the code in tests nvme/012 and nvme/013
to run an fio verify on a XFS file system backed by the
specified block device.

While we are at it, all the output is redirected to $FULL instead of
/dev/null.
