Log Message:
Make it work after lockmgr -> vlockmgr conversion:

- Initialize si_vnlock in si_mount_init().
  - Also initialize vl_recursecnt to zero.
- Destroy it only in si_mount_dtor().
- Simplify the v_lock <-> si_vnlock exchange.
- Don't abuse the overall error variable for LK_NOWAIT errors.
- ffs_snapremove: release the vnode one instead of three times.
