[action] [PR:19445] [Snappi] Fix tx/rx port sequence in test_pfc_port_congestion.py

[mssonicbld]

Description of PR

Summary:
Fixes the following issues in test_pfc_port_congestion.py:

1. Fixed the rx/tx port sequence, the currnet port_map is defined as [total egress port, egress port speed, total ingress ports, ingress port speed]. So get the rx port info from the first two elements.
2. pfcwd will be triggered on cisco platform as we are sending oversubscribed traffic, so disabling it during the test.

Type of change

• Bug fix
• Testbed and Framework(new/improvement)
• New Test case
• Skipped for non-supported platforms

Approach

What is the motivation for this PR?

Adopt this test case for 400G speed

How did you do it?

Fixed the case to use correct RX/TX port_map sequence. and disable pfcwd inside the test case.

How did you verify/test it?

Any platform specific information?

Supported testbed topology if it's a new test case?
