Olga Kornievskaia 6c3c870e8d nfsd: nfserr_jukebox in nlm_fopen should lead to a retry 
commit a082e4b4d0 upstream.

When v3 NLM request finds a conflicting delegation, it triggers
a delegation recall and nfsd_open fails with EAGAIN. nfsd_open
then translates EAGAIN into nfserr_jukebox. In nlm_fopen, instead
of returning nlm_failed for when there is a conflicting delegation,
drop this NLM request so that the client retries. Once delegation
is recalled and if a local lock is claimed, a retry would lead to
nfsd returning a nlm_lck_blocked error or a successful nlm lock.

Fixes: d343fce148 ("[PATCH] knfsd: Allow lockd to drop replies as appropriate")
