NFS: Ensure that rmdir() waits for sillyrenames to complete

If an NFS client does

mkdir("dir");
fd = open("dir/file");
unlink("dir/file");
close(fd);
rmdir("dir");

then the asynchronous nature of the sillyrename operation means that
we can end up getting EBUSY for the rmdir() in the above test. Fix
that by ensuring that we wait for any in-progress sillyrenames
before sending the rmdir() to the server.
