[PATCH] xfs: don't warn about page discards on shutdown

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

If we are doing a forced shutdown, we can get lots of noise about
delalloc pages being discarded. This is happens by design during a
forced shutdown, so don't spam the logs with these messages.
