nfsd41: use session maxreqs for sequence target and highest slotid 

This fixes a bug in the sequence operation reply.

The sequence operation returns the highest slotid it will accept in the future
in sr_highest_slotid, and the highest slotid it prefers the client to use.
Since we do not re-negotiate the session slot table yet, these should both
always be set to the session ca_maxrequests.
