drm/amdgpu: Fix TLB invalidation request when using semaphore
Use a more meaningful variable name for the invalidation request
that is distinct from the tmp variable that gets overwritten when
acquiring the invalidation semaphore.
Fixes: 4ed8a03740d0 ("drm/amdgpu: invalidate mmhub semaphore workaround in gmc9/gmc10")
