A workaround was introduced in commit 1fb710793ce2 ("drm/amdgpu: Enable
MES lr_compute_wa by default") to help with some hangs observed in gfx1151.
This WA didn't fully fix the issue. It was actually fixed by adjusting
the VGPR size to the correct value that matched the hardware in commit
cf326449637a5 ("drm/amdkfd: bump minimum vgpr size for gfx1151").
There are reports of instability on other products with newer GC microcode
versions, and I believe they're caused by this workaround. As we don't
need the workaround any more, remove it.
Fixes: cf326449637a5 ("drm/amdkfd: bump minimum vgpr size for gfx1151")
