nfsd: fix corrupted reply to badly ordered compound
[ Upstream commit 5b7b15aee641904ae269be9846610a3950cbd64c ]
We're encoding a single op in the reply but leaving the number of ops
zero, so the reply makes no sense.
Somewhat academic as this isn't a case any real client will hit, though
in theory perhaps that could change in a future protocol extension.
