Chuck Lever eb64cf964d NFS: State reclaim clears OPEN and LOCK state 
The "state->flags & flags" test in nfs41_check_expired_stateid()
allows the state manager to squelch a TEST_STATEID operation when
it is known for sure that a state ID is no longer valid.  If the
lease was purged, for example, the client already knows that state
ID is now defunct.

But open recovery is still needed for that inode.

To force a call to nfs4_open_expired(), change the default return
value for nfs41_check_expired_stateid() to force open recovery, and
the default return value for nfs41_check_locks() to force lock
recovery, if the requested flags are clear.  Fix suggested by Bryan
Schumaker.

Also, the presence of a delegation state ID must not prevent normal
open recovery.  The delegation state ID must be cleared if it was
revoked, but once cleared I don't think it's presence or absence has
any bearing on whether open recovery is still needed.  So the logic
is adjusted to ignore the TEST_STATEID result for the delegation
state ID.
