libusb_open returns LIBUSB_ERROR_NO_MEM for any error returned by
libusb20_dev_open. Map some of the key errors reported by libusb20_dev_open to
their LIBUSB counterparts. As a minumum:

LIBUSB_ERROR_BUSY
LIBUSB_ERROR_ACCESS
LIBUSB_ERROR_NO_DEVICE

The added granularity aids USB client software to give a better user
experience.
