This test tries to directly corrupt the CRC field of the primary
superblock by using xfs_io pwrite, but never syncs it to disk,
so it's quite likely that the mount will not see the bad data.

Some tests deliberately corrupt scratch devices and so will fail
the post-test check. Add a "_require_scratch_nocheck" helper
function for such tests to avoid false test failure detection.
Also, ensure that _notrun cleans up the trigger for the post-test
checks. Otherwise the next test to run may try to validate the
scratch/test devices even though they are not used by the test.
Further, _check_xfs_filesystem() causes check to exit if it finds a
corruption. This is extremely annoying as it terminates the entire
test run rather than just reporting that the test fails. Hence add
an "iam != check" test before exiting so that calls from tests will
cause the test to fail, but calls from check won't cause the harness
to exit.
There are still some tests that fail the scratch check, these are
not obvious test failures and so need further investigation to
determine the cause of the failures.

Failure message of mount has been changed since util-linux v2.21, to
something like:
mount: mount /dev/sda5 on /mnt/scratch failed: Structure needs cleaning
Filter the output to match the golden image for newer mount binary so
that both old and new version of mount work correctly.

the commit:
10e6e65 xfs: be more forgiving of a v4 secondary sb w/ junk in v5 fields
broke primary sb CRC validation, not erroring out the mount
if the crc was bad.
This tests that it's fixed, and properly fails the mount on
a bad crc.
