check: _check_filesystems for errors even if test failed

Previously, we would only run _check_filesystems to ensure that a test
that appeared to pass did not have any filesystem corruption. However,
in _check_filesystems, we also repair any errors found in the filesystem.
Let's do this even if we already know the test failed so that subsequent
tests aren't affected.
