selinux: don't reserve xattr slot when we won't fill it

Move lsm_get_xattr_slot() below the SBLABEL_MNT check so we don't leave
a NULL-named slot in the array when returning -EOPNOTSUPP; filesystem
initxattrs() callbacks stop iterating at the first NULL ->name, silently
dropping xattrs installed by later LSMs.
