be_sock: unfreeze buffers on fd changing

Only bufferevent_sock have evbuffer_freeze()/evbuffer_unfreeze() & ctrl ops, so
we don't need to fix other bufferevents (be_pair doesn't have ctrl op).

Found during draining buffers in http layer, and hence 501-not-implemented
error in regress http/.. (with some custom hacking).
