nfs: fix DIO good bytes calculation
For direct read that has IO size larger than rsize, we'll split
it into several READ requests and nfs_direct_good_bytes() would
count completed bytes incorrectly by eating last zero count reply.
Fix it by handling mirror and non-mirror cases differently such that
we only count mirrored writes differently.
This fixes 5fadeb47("nfs: count DIO good bytes correctly with mirroring").
