This is ultimately prep work for object reset locking, but valid on it's own: Make object dump routines utilize struct netlink_callback's scratch area for context data. This requires to relocate the s_idx counter, so turn nft_obj_filter into a real context data structure holding also the counter (and the reset boolean as well).
