Looking at other implementations of d_revalidate (ecryptfs, cifs, vfat)
it seems to be assumed that the inode is always valid.

I'd just remove the if, or if we keep it add a WARN or something for a
while so we can remove it in a few releases?

(That said, it's better to return 0 than 1 here, so don't take this for
a no -- progress is progress)
