nfsd: grant read delegations to clients holding writes
It's OK to grant a read delegation to a client that holds a write,
as long as it's the only client holding the write.
We originally tried to do this in commit 94415b06eb8a ("nfsd4: a
client's own opens needn't prevent delegations"), which had to be
reverted in commit 6ee65a773096 ("Revert "nfsd4: a client's own
opens needn't prevent delegations"").
