drm/amdgpu: fix TLB flushing during eviction

Browse source

Testing the valid bit is not enough to figure out if we
need to invalidate the TLB or not.

During eviction it is quite likely that we move a BO from VRAM to GTT and
update the page tables immediately to the new GTT address.

Rework the whole function to get all the necessary parameters directly as
value.
