Log Message:
Pull up following revision(s) (requested by hannken in ticket #309):
        sys/sys/vnode_impl.h: revision 1.17
        sys/kern/vfs_vnode.c: revision 1.99, 1.100

Change the VSTATE_ASSERT_UNLOCKED code by pushing the potential lock
handling into the backend and doing an optimistic (unlocked) check
first. Always taking the vnode interlock makes this assertion otherwise
very heavy for multi-processor machines.
-
Fix non-DIAGNOSTICS build by adjusting _vstate_assert here too.
