Subject: [PATCH 13/16] xfs: fix xfs_bmap_validate_extent_raw when checking
 attr fork of rt files

Source kernel commit: d0c20d38af135b2b4b90aa59df7878ef0c8fbef4

The realtime flag only applies to the data fork, so don't use the
realtime block number checks on the attr fork of a realtime file.

Fixes: 30b0984d9117 ("xfs: refactor bmap record validation")
