Subject: [PATCH] drm/i915/gvt: Don't mark vgpu context as inactive when preempted
Git-commit: ac7688c0397442f1c9eef7069737089660322497
Patch-mainline: v4.15-rc3
References: FATE#322643 bsc#1055900
No-fix: da5f99eaccc10e30bf82eb02b1be74703b878720
We shouldn't mark inactive for vGPU context if preempted,
which would still be re-scheduled later. So keep active state.
Fixes: d6c0511300dc ("drm/i915/execlists: Distinguish the incomplete context notifies")
