In IETF quic, start peer migration by switching peer address as soon as detecting a non-probing frame in the incoming packet rather than after finishing parsing the whole packet. Protected by --gfe2_reloadable_flag_quic_start_peer_migration_earlier.
Doing so will fix the bug in IETF QUIC that a server may send in-cache response to old address while the end of current packet processing isn't reached
