anv: prepare driver to report submission error through queues

When we will submit to i915 from a submission thread, we won't be able
to directly report the error to the user (in particular through the
debug report callbacks). So prepare 2 paths to report errors device ->
notifying the user immediately, queue -> notifying the user the next
time an entry point is called.

In this change we still report directly for both paths, this will
change in the next commit.

v2: Split NULL batch parameter handling in
    anv_queue_submit_simple_batch() in a different commit
