don't shrink file in nfs_close() for NFSv4

If an NFSv4 server replies with a size smaller than what it currently is
for a file when doing an VOP_CLOSE(), the client erroneously would believe
this smaller size. This bug was only observed during testing of a broken
server, but this patch fixes it in any case.
