In the PCI hotplug path of the Intel IOMMU driver, replace the usage of the BUS_NOTIFY_DEL_DEVICE notifier, which is executed before the driver is unbound from the device, with BUS_NOTIFY_REMOVED_DEVICE, which runs after that. This fixes a kernel BUG being triggered in the VT-d code when the device driver tries to unmap DMA buffers and the VT-d driver already destroyed all mappings.
