[PATCH 4/5] xfs_scrub: don't fail while reporting media scan errors

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

If we can't open a file to report that it has media errors, just log
that fact and move on.  In this case we want to keep going with phase 6
so we report as many errors as possible.
