usbip: adding names db to port operation

Adding names database to port command.

BEFORE) 'unknown' for vendor and product string.

Imported USB devices
====================
Port 00: <Port in Use> at Low Speed(1.5Mbps)
       unknown vendor : unknown product (03f0:0224)
       3-1 -> usbip://10.0.2.15:3240/5-1
           -> remote bus/dev 005/002

AFTER) Most vendor string will be converted.
