[PATCH 4.19 45/88] xfs: fix xfs_bmap_validate_extent_raw when checking attr fork of rt files

[Greg Kroah-Hartman]

From: Darrick J. Wong <darrick.w...@oracle.com>

[ Upstream 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")
