Subject: [PATCH] dev-amdgpu: Correct missing GART warning

SDMA ptePde packets are generating a warning that a GART address is
missing, causing a wrong address to be clobbered by the operation.

This commit fixes this by converting the GART address when the queue is
running in privledged mode, which is the only mode allowed to use GART
addresses. This removes the warnings and writes to the correct memory
region.
