[Mellanox] Fix issues found for CMIS host management (#17637)
- Why I did it
1. Thermal updater should wait more time for module to be initialized
2. sfp should get temperature threshold from EEPROM because SDK sysfs is not yet supported
3. Rename sfp function to fix typo
4. sfp.get_presence should return False if module is under initialization

- How I did it
1. Thermal updater should wait more time for module to be initialized
2. sfp should get temperature threshold from EEPROM because SDK sysfs is not yet supported
3. Rename sfp function to fix typo
4. sfp.get_presence should return False if module is under initialization

- How to verify it
