fix USB devices with multiple configurations
This patch fixes bugs in usbdcore*.c related to the use of devices
with multiple configurations.
The original code made mistakes about the meaning of configuration value and
configuration index, and the resulting off-by-one errors resulted in:
* SET_CONFIGURATION always selected the first configuration, no matter what
wValue is being passed.
* GET_DESCRIPTOR/CONFIGURATION always returned the descriptor for the first
configuration (index 0).
