[Nut-upsdev] PowerWare USB debug messages

[Charles Lepple]

Earlier this year, I added a patch to my local NUT tree to
additionally print the value of usb_strerror() if usb_clear_halt()
failed.

(Ignore the commented-out goto.)

Since these messages are at the LOG_ERR level, should we add
usb_strerror() to all of the calls in nut_usb.c?

        return dev_h;
