Some fixes for compilation errors

[bWolfie]

I will list some stuff which gives compilation errors.

1. status_get_guild_id_pre
   Change this line
   && (bg_id = bg->team_get_id((struct block_list *)*bl)) > 0
   to
   && (bg_id = bg->team_get_id((struct block_list *)bl)) > 0

2. status_get_emblem_id_pre
   Change this line
   && (bg_id = bg->team_get_id((struct block_list *)(*bl))) > 0
   to
   && (bg_id = bg->team_get_id((struct block_list *)bl)) > 0

3. In ACMD(reportafk) and ACMD(leader) there are unused definitions:
   struct hBG_map_session_data *hBGsd = NULL;

When I apply this fix, the emblem problem here #39 occurs.
