config_intrhook_drain will remove the hook from the list as config_intrhook_disestablish does if the hook hasn't been called. If it has, config_intrhook_drain will wait for the hook to be disestablished in the normal course (or expedited, it's up to the driver to decide how and when to call config_intrhook_disestablish). This is intended for removable devices that use config_intrhook and might be attached early in boot, but that may be removed before the kernel can call the config_intrhook or before it ends. To prevent all races, the detach routine will need to call config_intrhook_train.
