"count_matched_packets" method is getting stuck in a while loop as long as ptf server port receives any packet (Ex: in dualtor case, we do see continuous ICMP packets on ptf port). Fix is to consider only expected packets w.r.t timeout (similar to "count_matched_packets_all_ports" logic). Signed-off-by: Vinod <vkjammala@arista.com>

I would also like to note that the same logic (added in this PR) is already present in count_matched_packets_all_ports |

count_matched_packetsmethod is getting stuck in a while loop as long as ptf port receives any packet (Ex: in certain testing topologies, protocol packets (like ICMP) on ptf port are causingcount_matched_patchesmethod to stuck waiting for packet poll to fail). Fix is to consider only expected packets w.r.t timeout (similar to existingcount_matched_packets_all_portslogic).See sonic-net/sonic-buildimage#21150 for more details on why this fix is needed.
