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.
