[PATCH] xfs: remove xfs_bmap_sanity_check()

To: xfs@xxxxxxxxxxx
Subject: [PATCH] xfs: remove xfs_bmap_sanity_check()
From: Dave Chinner <david@xxxxxxxxxxxxx>
Date: Wed, 25 Feb 2015 17:41:10 +1100
Delivered-to: xfs@xxxxxxxxxxx
From: Dave Chinner <dchinner@xxxxxxxxxx>

This code is redundant now that we have verifiers that sanity check
the buffers as they are read from disk.
