This test is always true so it means we revalidate the length every
time, which generates more network traffic. This was introduced in
06222e491e "fs: handle SEEK_HOLE/SEEK_DATA properly in all fs's that
define their own llseek".

Josef, there were three other places that had this same problem but I
think they've all been fixed now. Except that I had a question about
nfs_file_llseek(). Isn't that reversed? It seems like it only
revalidates when it's not supposed to. I chose to copy what
fuse_file_llseek() does instead.
