LU-5396 mdc: add sparse annotation __user wherever needed

This fixes sparse warnings such as:

  .../api-ni.c:1639:33: warning: incorrect type in argument 3
                             (different address spaces)
  .../api-ni.c:1639:33:    expected struct lnet_process_id_t
                             [noderef] [usertype] <asn:1>*ids
  .../api-ni.c:1639:33:    got struct lnet_process_id_t
                             [usertype] *<noident>

There is no code change.
