[PATCH 26/48] xfsprogs: disable xfs_check for CRC enabled filesystems

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

Until xfs_db has full metadata CRC support, xfs_check will not be
able to fully verify filesystems in this format. Don't even
bother trying right now, and to make it simple to test full xfsprogs
installs with xfstests, just silently succeed.
