From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxx>
All apart from AMDGPU_GEM_DOMAIN_GTT memory domains map 1:1 to TTM
placements. And the former be either AMDGPU_PL_PREEMPT or TTM_PL_TT,
depending on AMDGPU_GEM_CREATE_PREEMPTIBLE.
Simplify a few places in the code which convert the TTM placement into
a domain by checking against the current placement directly.
In the conversion AMDGPU_PL_PREEMPT either does not have to be handled
because amdgpu_mem_type_to_domain() cannot return that value anyway.
v2:
* Remove AMDGPU_PL_PREEMPT handling.
