[202012] [Mellanox] Fix issue: cannot lable port for logical port is logical port number larger than 64 (#13709)

Browse Source 
- Why I did it
sfp_event.py gets a PMPE message when a cable event is available. In PMPE message, there is no label port available. Current sfp_event.py is using sx_api_port_device_get to get 64 logical ports attributes, and find the label port from those 64 attributes. However, if there are more than 64 ports, sfp_event.py might not be able to find the label port and drop the PMPE message.

- How I did it
Don't use hardcoded 64, get logical port number instead.

- How to verify it
Manual test
