[PATCH 1/1] iommu/vt-d: Make context clearing consistent with context mapping

[Lu Baolu <baolu.lu@linux.intel.com>]

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.

Fixes: 579305f75d34 ("iommu/vt-d: Update to use PCI DMA aliases")
