HID: roccat: Fix NULL pointer dereference when unloading module

Browse Source 
Class was destroyed before starting the unregistering driver chain.
Disconnecting a device from roccat chardev in this process then
raised a NULL pointer dereference.
Fixed this by destroying class after unregistering driver.
