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

Log Message:
Fix a race condition where a writer could already have closed the fifo
before the reader woke up - this made the reader loop again, waiting
for another writer, even though there was input available.

Thanks to Jaromir for spotting the real cause and sugesting a solution.

This should fix PR port-sparc64/20283.
