Description
When the CMIS cable EEPROM is not ready,
get_transceiver_infoshould return None to notify XCVRD that cable EEPROM is not ready instead of returning a dictionary including 'None' values.If any field is 'None', we consider the CMIS cable EEPROM is not fully ready yet.
Motivation and Context
get_transceiver_infoshould return a dictionary including the correct field and values to XCVRD, if EEPROM is not ready should not return a dictionary with incorrect values. The 'None' return value can trigger XCVRD to start the retry EEPROM reading flow.This is also to fix issue sonic-net/sonic-buildimage#11525
How Has This Been Tested?
keep run sfputil reset test case and see no further crash.
