iommu: Remove useless flush from iommu_create_device_direct_mappings()
These days iommu_map() does not require external flushing, it always
internally handles any required flushes. Since
iommu_create_device_direct_mappings() only calls iommu_map(), remove
the extra call.
Since this is the last call site for iommu_flush_iotlb_all() remove it
too.
