This patch addresses two issues in fixes offset mappings:
- VA unmapping did not use lists safely. This caused an application hang
if the application did not free all (fixed offset) buffers before quiting.
- GPU was not powered closing AS node. If the address space had areas that
were not freed, the driver tried to access hw without powering it up first.
