From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>
Move all the requirements checking for xfs_scrub into a helper function.
Make sure the helper properly detects the presence of the scrub ioctl
and situations where we can't run scrub (e.g. norecovery).
Refactor the existing three xfs_scrub call sites to use the helper to
check if it's appropriate to run scrub.
