v11:

• Drop hw_error field in vtd cache invalidation uapi. devTLB invalidation error is a serious security emergency requiring the host kernel to handle. No need to expose it to userspace (especially given existing VMs doesn't issue devTLB invalidation at all).
• The vtd qi_submit_sync() and related callers are reverted back to the original state due to above drop.
• Align with the vtd path, drop the hw_error reporting in mock driver and selftest as well since selftest is a demo of the real driver.
• Drop iommu_respond_struct_to_user_array() since no more driver want to respond single entry in the user_array.
• Two typos from Wubinbin

Okay, this is very last minute but I updated the series.
