xfs: reject unknown xattri log item filter flags during recovery
Make sure we screen the "attr flags" field of recovered xattr intent log
items to reject flag bits that we don't know about. This is really the
attr *filter* field from xfs_da_args, so rename the field and create
a mask to make checking for invalid bits easier.
