intel-iommu: Clean up handling of "caching mode" vs. context flushing.
It really doesn't make a lot of sense to have some of the logic to handle caching vs. non-caching mode duplicated in qi_flush_context() and __iommu_flush_context(), while the return value indicates whether the caller should take other action which depends on the same thing. Especially since qi_flush_context() thought it was returning something entirely different anyway. This patch makes qi_flush_context() and __iommu_flush_context() both return void, removes the 'non_present_entry_flush' argument and makes the only call site which _set_ that argument to 1 do the right thing.
