Fix a bug that occurs when a FIFO is opened for writing with
O_NONBLOCK set and there are no readers. Before returning ENXIO
fifo_open calls VOP_CLOSE (and hence fifo_close). However, since
fi_writers has not yet been incremented, when fifo_close decements
fi_writers it is one too few. This could cause qmail processes
to spin, consuming all the CPU.
Noticed by avsm@ and henning@, test case provided by claudio@, Ok pedro@
