drm/amdkfd: Block per-queue reset when halt_if_hws_hang=1

commit f214b7beb00621b983e67ce97477afc3ab4b38f4 upstream.

The purpose of halt_if_hws_hang is to preserve GPU state for driver
debugging when queue preemption fails. Issuing per-queue reset may
kill wavefronts which caused the preemption failure.
