H A Ddirect.cdiff eb79f3af9395fbe448e91b0940a6c395b7d06be4 Mon May 09 20:20:48 CDT 2022 NeilBrown <neilb@suse.de> nfs: rename nfs_direct_IO and use as ->swap_rw

The nfs_direct_IO() exists to support SWAP IO, but hasn't worked for a
while. We now need a ->swap_rw function which behaves slightly
differently, returning zero for success rather than a byte count.

So modify nfs_direct_IO accordingly, rename it, and use it as the
->swap_rw function.
