Modified Files:
	syssrc/sys/miscfs/fifofs: fifo_vnops.c

Log Message:
we can't use the vnode's v_usecount to track how many times the vnode
has been VOP_OPEN()'d.  if the fifo is being accessed via a layered fs,
v_usecount is always one (representing the hold by the layered vnode)
regardless of how many times the vnode has been opened.  instead, keep a
separate counter for opens.  fixes PR 17195 and probably 17724.
