NFSv4.1: keep seq_res.sr_slot as pointer rather than an index
Having to explicitly initialize sr_slotid to NFS4_MAX_SLOT_TABLE resulted in numerous bugs. Keeping the current slot as a pointer to the slot table is more straight forward and robust as it's implicitly set up to NULL wherever the seq_res member is initialized to zeroes.
