xfs: clear kernel only flags in XFS_IOC_ATTRMULTI_BY_HANDLE
commit 953aa9d136f53e226448dbd801a905c28f8071bf upstream.
Don't allow passing arbitrary flags as they change behavior including
memory allocation that the call stack is not prepared for.
Fixes: ddbca70cc45c ("xfs: allocate xattr buffer on demand")
