NFSv4: Ensure that we recover from the OPEN + OPEN_CONFIRM BAD_STATEID race
If the server is in the unconfirmed OPEN state for a given open owner
and receives a second OPEN for the same open owner, it will cancel the
state of the first request and set up an OPEN_CONFIRM for the second.
This can cause a race that is discussed in rfc3530 on page 181.
The following patch allows the client to recover by retrying the
original open request.
