Message:

VBoxUSB/darwin: Fix issues grabbing certain interfaces after the guest issued a SET_CONFIGURATION request to a grabbed device on El Capitan.

The SET_CONFIGURATION request causes a probing of all interfaces for matching drivers. Because IOUSBUserClientInit::probe() returns NULL
on El Capitan (10.11) VBox fails to hijack the interface and other drivers might get a shot blocking access to the interface and breaking USB
passthrough.
This is an amendment of r102968
