Konstantin Belousov f5eb95b1fc Allow shared-locked vnode to be passed to vunref(9).
When shared-locked vnode is supplied as an argument to vunref(9) and
resulting usecount is 0, set VI_OWEINACT and do not try to upgrade vnode
lock. The later could cause vnode unlock, allowing the vnode to be
reclaimed meantime.
