PRT support for amdgpu v3

Hi,
Some more testing uncovered a bug in cleanup paths. When the application
segfaults while PRT mappings exist, I get a WARN_ON (which seems fairly
straightforward) and occasionally also an RCU error warning -- see the
attached dmesg logs.
Regular application shutdown works fine, though.
Cheers,
Nicolai
