drm/i915/gvt: Refine error handling in dispatch_workload
When an error occurs in dispatch_workload, this patch is to do the
proper cleanup and rollback to the original states before the workload
is abandoned.
v2:
- split the mixed several error paths for better review. (Zhenyu)
v3:
- original PTR_ERR(cs) is good and code cleanup. (Zhenyu)
v4:
- reuse the existing i915_add_request for error handling. (Zhenyu)
v5:
- remove the duplicate error handling release_shadow_wa_ctx and
move the engine->context_unpin upper. (Zhenyu)
v6:
- keep the old label "out". (Zhenyu)
