drm/i915/gvt: add a NULL pointer check to avoid kernel panic
Due to the request replay, context switch interrupt may come after
gvt free the workload thus can cause a kernel NULL pointer kernel
panic. This patch will add a simple check to avoid this for a short
term.
From long term, gvt workload lifecycle doesn't match with i915 request
and need to find a proper way to manage this.
v4: simplify the NULL pointer check.
v5: add unlikely to optimize.
