[ssd_generic]Fix ssd no vendor information

The ssd information can show correctly even if can't get model information in generic SSD information.
When unknown model name , use Virtuim tool to get SSD Health/Temperature .

How has this been Tested ?
Manual testing on Edgecore switch (ex AS4630_54PE)
