iommu/vt-d: Make context clearing consistent with context mapping

[ Upstream commit 9a16ab9d640274b20813d2d17475e18d3e99d834 ]

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.
