drm/amdgpu: keep vm in job instead of ib
ib.vm is a legacy way to get vm, after scheduler
implemented vm should be get from job, and all ibs
from one job share the same vm, no need to keep ib.vm
just move vm field to job.
this patch as well add job as paramter to ib_schedule
so it can get vm from job->vm.
Easy to provoke with powerplay=1 and auto clocks. Harder to provoke, but also
happens with powerplay=0.
dmesg with Oops attached.
