Subject: [PATCH v1 1/3] xfs/539: Skip noattr2 remount option on v5 filesystems

This test is to verify that repeated warnings are not printed
for default options (attr2, noikeep) and warnings are
printed for non default options (noattr2, ikeep). Remount
with noattr2 fails on a v5 filesystem, so skip the mount option.
