usb: quirks: add quirk for WORLDE MINI MIDI keyboard

This keyboard doesn't implement Get String descriptors properly even
though string indexes are valid. What happens is that when requesting
for the String descriptor, the device disconnects and
reconnects. Without this quirk, this loop will continue forever.
