[PATCH 3/4] usb: usbtmc: add Rigol DP800 and DS1000Z to the packet I/O quirk table

[Nicolai Buchwitz]

The Rigol DP800 power supply and DS1000Z oscilloscope families also
advertise 64-byte bulk endpoints at high speed. Replies are cut off
after the first packet, and writes larger than 64 bytes fail on the
DP800:

  usbtmc 1-1.3:1.0: Unable to send data, error -71

Tested on a DP832A and a DS1054Z.
