commit 8ef1d96a985e4dc07ffbd71bd7fc5604a80cc644 upstream.

The XFS_SB_FEAT_INCOMPAT_LOG_XATTRS feature bit protects a filesystem
from old kernels that do not know how to recover extended attribute log
intent items.  Make this check mandatory instead of a debugging assert.

Fixes: fd920008784ea ("xfs: Set up infrastructure for log attribute replay")
