xfs: require XFS_SB_FEAT_INCOMPAT_LOG_XATTRS for attr log intent item recovery

Browse Source 
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: fd92000878 ("xfs: Set up infrastructure for log attribute replay")
