libusb-compat-0.1 devices still referenced upon exit

[mcuee]

Reference:

• libusb-compat-0.1 devices still referenced upon exit libusb#988
• Better cleanup upon libusb_close() and libusb_exit() libusb#974

I am not so sure if this is an issue with libusb-compat-0.1 or libusb.

The following fix to libusb-compat-0.1 seems to fix the issue. But I am not so sure if it is the right fix or not.

Please take a look at the proposed fix. Thanks. It seems to me this is not a bug of libusb but rather libusb-compat-0.1.

@tormodvolden and @hjelmn

Just wondering if you have some comments of this long standing issue. Thanks.
