kernel - Fix hammer flush-during-reclaim bug
* hammer was improperly using vn_unlock/vn_lock to temporarily unlock a
vnode. If this is done during a reclaim vn_lock() will fail, resulting
in a locking mismatch.
* Use vx_unlock/vx_lock instead, and also check for the reclaim by checking
the VRECLAIMED flag rather than the VINACTIVE flag. VINACTIVE might not
yet be set.
