xfs/189: noattr2 invalid for CRC enabled filesystems

Version 5 filesystems always have attr2 format enabled, and it
cannot be turned off via the noattr2 mount option. As such, attempts
to mount with noattr2 will be rejected and this causes cascading
failures within the test.

Hence detect if we've created a CRC enabled filesystem, and if this
is the case _notrun the test.
