tail -f doesn't work as expected with npfs #3

Here's the scenario. Mount a server, tail -f an existing file, then append to that file on the server host...tail -f will never see the result. Originally discovered with npfs (9p2000 only)

verified this with diod as well. Not sure if problem is in file server or kernel, but appears in both 9p2000 and 9p2000.L variants.
