[PATCH 12/13] xfs_scrub: move all the queue_subdir error reporting to callers

["Darrick J. Wong" <darrick.wong@oracle.com>]

From: Darrick J. Wong <darrick.wong@oracle.com>

Change queue_subdir to return a positive error code to callers and move
the error reporting to the callers.  This continues the process of
changing internal functions to return error codes.
