genetlink: register family ops as array
Instead of using a linked list, use an array. This reduces the data size needed by the users of genetlink, for example in wireless (net/wireless/nl80211.c) on 64-bit it frees up over 1K of data space. Remove the attempted sending of CTRL_CMD_NEWOPS ctrl event since genl_ctrl_event(CTRL_CMD_NEWOPS, ...) only returns -EINVAL anyway, therefore no such event could ever be sent.
