Chassis: test_show_pfc_counters fails since show pfc counters does not include inband and recycle ports

Description

test_show_pfc_counters fails since show pfc counters does not include inband and recycle ports.
"show interface counters" includes inband and recycle ports and it passes

mode = 'alias'
It searches for each alias from port_alias_map in the output of "SONIC_CLI_IFACE_MODE=alias sudo show pfc counters"
It does not find aliases associated with Inband ports (Ethernet-IB0, Ethernet-IB1) or recycle ports (Ethernet-Rec0, Ethernet-Rec1) in pfc_rx or pfc_tx counters

mode = 'default'
It searches for each interface from port_name_map in the output of "SONIC_CLI_IFACE_MODE=default sudo show pfc counters"
It does not find Inband ports (Ethernet-IB0, Ethernet-IB1) or recycle ports (Ethernet-Rec0, Ethernet-Rec1) in pfc_rx or pfc_tx counters

Steps to reproduce the issue:

1. Run test_show_pfc_counters

Describe the results you received:

E AssertionError
ifmode = 'default'
intf = 'Ethernet-Rec1'

checking for 'Ethernet-Rec1 in the output of show pfc counter but it does not exist.

Describe the results you expected:

No AssertionError

@vmittal-msft please see if any particular handling is needed for Recycle and Inband ports from PFC perspective.
