darwin: do not reset darwin_cached_devices on last call to libusb_exit

This fixes a bug in the change that removed the library destructor function. We should not
be setting the darwin_cached_devices next and prev pointers to NULL as other parts of
libusb may still have references to the devices (hotplug for example). When those references
are release it may modify darwin_cached_devices. This commit fixes the issue by only
initializing darwin_cached_devices on the very first call to libusb_init and not modifying
darwin_cached_devices in libusb_exit (beyond unrefing the devices).
