A next patch will emit more instructions in video and copy queues
for Gfx 200 and newer but the current code only creates anv_async_submit
if device has aux_map.
Instead we can always create anv_async_submit and only submit it to
hardware if any instruction was emited.
Fixes: 86813c60a4 ("mi-builder: add read/write memory fencing support on Gfx20+")
