nfs41: Don't clear DRAINING flag on NFS4ERR_STALE_CLIENTID

If CREATE_SESSION fails with NFS4ERR_STALE_CLIENTID, don't clear the
NFS4CLNT_SESSION_DRAINING flag and don't wake RPCs waiting for the
session to be reestablished.  We don't have a session yet, so there
is no reason to wake other RPCs.

This avoids sending spurious compounds with bogus sequenceID during
session and state recovery.
