Subject: drm/i915/selftests: Take a VM in kernel_context()
Git-commit: 5888d588597408ea8208e89497dbbdb72d405071
Patch-mainline: v5.15-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
This better models where we want to go with contexts in general where
things like the VM and engine set are create parameters instead of being
set after the fact.
