drm/amdgpu/mes_v12_0: use mes schedule pipe for legacy queues on unified MES

Browse source

when suspend_all_gangs is issued to pipe0 MES during system suspend or runtime PM, pipe0 can only suspend and resume queues it has tracked.
KCQs registered with a non-zero pipe slot may not be correctly handled, leaving them in an inconsistent state after resume.

v3: fix the schedule pipe issue
v4: use schedule pipe for KQ resets
