drivers/libusb{0,1}.c: reset driver parameters while enumerating
With an Arduino Leonardo compatible board attached alongside a CyberPower CP1500PFCLCD, usbhid-ups would incorrectly conclude that there was no kernel driver attached to the UPS and then fail subsequent steps accordingly. The cause is the global usb_communication_subdriver_t struct; when a subdriver (e.g. arduino-hid) sets different values during the enumeration loop, they're not set back to defaults afterwards, causing issues with other subdrivers (e.g. cps-hid). So, if a subdriver doesn't match, set a selection of fields back to their default values using the newly added nut_usb_subdriver_defaults() before the next attempt.
