LinuxKPI: disable device_release_driver()

As reported by multiple people testing iwlwifi, device_release_driver()
can lead to a panic on secondary errors (usually during attach).
Disable device_release_driver() for the short-term to prevent the panic
but leave it in place so it can be re-worked and fixed properly for
the long-term more easily.
