We made nfs4_delegation_exists() return a bool in 68b18f52947b ("nfsd:
make nfs4_get_existing_delegation less confusing"), but it's still
returning -EINVAL. That's fine, because it -EINVAL becomes true which
is what we want, but it's not very tidy.

Oops, I fixed this a couple days ago when Fengguang Wu complained about
the 0/false thing, but forgot to push it out. Added a Reported-by: for
you and pushed it out now to
git://linux-nfs.org/~bfields/linux.git nfsd-next
