mds: set the loner to true for LOCK_EXCL_XSYN

For filelock when in LOCK_EXCL_XSYN state the non-loner clients
should be issued empty caps, but since the loner of this state
is set to false and it could make the Locker to issue the Fcb caps
to them, which is incorrect.

This fix will just set the loner to true.
