NFSv4: Fix a BAD_SEQUENCEID condition.

Browse Source 
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.
