[XFS] Fix up noattr2 so that it will properly update the versionnum and
features2 fields. Previously, mounting with noattr2 failed to achieve anything because although it cleared the attr2 mount flag, it would set it again as soon as it processed the superblock fields. The fix now has an explicit noattr2 flag and uses it later to fix up the versionnum and features2 fields.
