xfs_scrub: don't report data loss in unlinked inodes twice

If parent pointers are enabled, report_ioerr_fsmap will report lost file
data and xattrs for all files, having used the parent pointer ioctls to
generate the path of the lost file.  For unlinked files, the path lookup
will fail, but we'll report the inumber of the file that lost data.

Therefore, we don't need to do a separate scan of the unlinked inodes
in report_all_media_errors after doing the fsmap scan.
