etcp: убрать ложный reinit по gop (got_initial_pkt)

reinit должен происходить только при смене reset_id пира
(etcp_conn_apply_peer_reset_id). gop-проверка 'dirty vs clean' на догоняющем
TCP-линке давала ложный reinit и рвала соединение (JOIN_INFO_RESP терялся).
Удалён peer_got_initial_pkt из stcp_link (стал не нужен).
