ss: Log warning instead of return error

This commit changes the logic of `parseComDetail` function
to log warning when can't extract service name, and set it
to empty, instead of returning an error.

This is to prevent the matrix generation from failing due to
an `SS` entry without a service name like the following:
`UNCONN 0      0           [::]:6081     [::]:*  `
