protodetect: be more tolerant

Do not mask protocols on both directions with only first packet

For instance :
When the first packet is no valid DNS but on port 53 (a junk request)
second packet (error response from server) does not get checked for DNS
as first packet bit masked away DNS for both directions

Ticket: #2757
