Remove check against passed bufferevent in bufferevent_socket_connect() It is a bit confusing to check against the result of EVUTIL_UPCAST(), because it can return not NULL for NULL pointers, but for even though with bufferevent we are fine (because bufferevent is the first field in bufferevent_private), there are no checks for "bufev" in bufferevent's API, so just remove it to make it generic.
