Modified Files:
	src/sys/fs/puffs: puffs_subr.c

Log Message:
Apply a little eggwash to a deadlock condition where calling
getnewvnode() while holding on to any vnode lock deadlocks the
system if the file system is being forcibly unmounted.

Normal file systems don't trigger this problem because of two reaons:
1) they don't hold on to vnode locks while idling who-knows-where, so
   the race doesn't trigger
2) they aren't usually unmounted with FORCE; puffs is, in case "someone"
   manages to make a crashy userspace server

Nevertheless, a real solution is slowly being braised.
