drm/amdgpu: remove VI hw bug workaround v3
The workaround simply doesn't work because VM mappings
are controlled by userspace not the kernel.
Additional to that this is just a performance problem
which happens if you have holes in your VM mapping.
v2: adjust virtual addr alignment as well.
v3: fix trivial warning
