drm/amdkfd Avoid destroy hqd when GPU is on reset

This reverts commit 5161bba4311f in order to split it into two
different patches, and this will make it easier to understand.

[PATCH 1/2]
porting to gfx10 from
commit 1b0bfcff463f390c40 ("drm/amdgpu: Avoid destroy hqd when GPU is on reset")

Originally, MEC is touched
without GPU initialized first.
