nfs: increment i_dio_count for reads, too i_dio_count is used to protect dio access against truncate. We want to make sure there are no dio reads pending either when doing a truncate. I suspect on plain NFS things might work even without this, but once we use a pnfs layout driver that access backing devices directly things will go bad without the proper synchronization.
