NFSv4: Fix a BAD_SEQUENCEID condition.
We really shouldn't be resetting the sequence ids when doing state expiration recovery, since we don't know if the server still remembers our previous state owners. There are servers out there that do attempt to preserve client state even if the lease has expired. Such a server would only release that state if a conflicting OPEN request occurs.
