NFSv4: Fix open create exclusive when the server reboots
[ Upstream commit 8fd1ab747d2b1ec7ec663ad0b41a32eaa35117a8 ]
If the server that does not implement NFSv4.1 persistent session
semantics reboots while we are performing an exclusive create,
then the return value of NFS4ERR_DELAY when we replay the open
during the grace period causes us to lose the verifier.
When the grace period expires, and we present a new verifier,
the server will then correctly reply NFS4ERR_EXIST.
This commit ensures that we always present the same verifier when
replaying the OPEN.
