usb: Remove obsolete Huawei 3G from usbdevs

• remove Huawei 3G E3131 (E3131_INIT):
  • frees up 0x1505/0x14fe shared IDs => product is EOL (since...)
  • 3G networks are shutdown/scheduled
  • E3131 devices will still work the same via scsi_huawei_eject2
  • new 4G devices will switch & report correctly now
