[202405] [xcvrd] Fix issue: do not print error log when module support non-ethernet application

[Junchao-Mellanox]

Backport #501

Description

In function get_interface_speed, it will log an error if the application name does not contain a valid speed. However, many modules support both ethernet and non-ethernet (e.g. IB) application, non-ethernet application would not contain a valid speed. For such module, the function get_interface_speed logs an error to syslog:

Jun 12 20:09:57.315556 sonic ERR pmon#xcvrd: No interface speed found for: 'IB HDR (Arch.Spec.Vol.2)'

Actually, this is not an error because the module will finally find a proper application via the for loop in function get_cmis_application_desired

Motivation and Context

Remove the unexpected error log since it could be a false alarm. Also, log the module applications if it cannot find a proper application.

How Has This Been Tested?
