xfs: take hm->lock in xfs_ioc_health_monitor() before insert

Browse source

__xfs_healthmon_insert() asserts that hm->lock is held
(lockdep_assert_held), but xfs_ioc_health_monitor() called it right
after allocating hm, before ever taking the lock, triggering a
lockdep warning.

Take hm->lock around the call.
