Cleanup functions can run even if the _require functions decide to
_notrun the test, so I think this ought to be:

	test -w /sys/fs/xfs/debug/larp && \
		echo 0 > /sys/fs/xfs/debug/larp

This only tests that the sysfs control file exists, not that it's
writable.  Granted, debug knobs are writable by default, but we should
be careful here and:

test -w /sys/fs/xfs/debug/larp || _notrun "larp knob not writable"

So this test won't fail if (say) someone has chmod a-w the debug knob
since the module loaded.

With that fixed, I think this test will be ready to go the next time
around.
