usbtmc: only reset Siglent (and Atten) devices in open

Make the USB reset for USB TMC devices conditional. Check a whitelist,
which in this implementation exclusively contains the Siglent VID.

The whitelist's comment may need adjustment. The VID probably not only
applies to SDS devices, but could be used for SDG and others as well.
And lsusb output suggests the VID is used by Atten, too.
