Modified Files:
        src/sys/kern: vfs_vnode.c

Log Message:
Change vrelel() to mark the vnode as changing after it has aquired
the vnode lock but before it calls VOP_INACTIVE().

Should fix the race between layer_node_find() trying to vget(, LK_NOWAIT)
a locked vnode when vrelel() marked it as changing and wants its lock.

PR kern/48411 (repeatable SMP crashes in amd64-current)
