sunrpc: Simplify auth_unix now that everything is a kgid_t
In unx_create_cred directly assign gids from acred->group_info to cred->uc_gids. In unx_match directly compare uc_gids with group_info. Now that both group_info and unx_cred gids are stored as kgids this is valid and the extra layer of translation can be removed. Cc: "J.
