[PATCH 14/36] xfs: don't emit corruption noise on fs probes

[Dave Chinner <david@xxxxxxxxxxxxx>]

From: Dave Chinner <dchinner@xxxxxxxxxx>

If we get EWRONGFS due to probing of non-xfs filesystems,
there's no need to issue the scary corruption error and backtrace.

Ported from kernel commit 31625f28.
