NFSv4: Fix another open/open_recovery deadlock
If we don't release the open seqid before we wait for state recovery, then we may end up deadlocking the state recovery thread. This patch addresses a new deadlock that was introduced by commit c21443c2c792cd9b463646d982b0fe48aa6feb0f (NFSv4: Fix a reboot recovery race when opening a file) Reported-by: Andy Adamson <andros@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
