[PATCH 27/32] xfs: don't check secondary super inode pointers when metadir enabled

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

From: Darrick J. Wong <djwong@xxxxxxxxxx>

When metadata directories are enabled, the rt and quota inodes are no
longer pointed to by the superblock, so it doesn't make sense to check
these.
