- Re-order functions in cistpl.c.
- Combine setup_cis_mem and set_cis_map into one function.
- Move cis_readable(), checksum() and checksum_match() into rsrc_mgr.c
- Only pass the socket structure to validate_mem()
- Remove socket_info_t *vs variable, and the race condition along
  with it.
- Pass the socket_info_t through validate_mem(), do_mem_probe() and
  inv_probe() to these functions.
- Call cis_readable() and checksum_match() directly from
  do_mem_probe().
