iommu/vt-d: Make context clearing consistent with context mapping
In the iommu probe_device path, domain_context_mapping() allows setting up the context entry for a non-PCI device. However, in the iommu release_device path, domain_context_clear() only clears context entries for PCI devices. Make domain_context_clear() behave consistently with domain_context_mapping() by clearing context entries for both PCI and non-PCI devices.
