fix: memory pool alloc mismatch in tests, db_sync SEND_DATA buffer overflow

- test_etcp_router_reconnect, test_etcp_connect, test_stcp_traffic:
  replace u_calloc with memory_pool_alloc for TOPO_SOCKMETA4/TOPO_ADDR4
- db_sync.c: fix req[14] -> req[15] — SEND_DATA request header is 15 bytes
  (type:1 + from:4 + count:2 + vp:4 + want_from:4)
