[Intel-gfx] [PATCH 10/27] drm/i915/selftests: Skip live context execution test without logical contexts

[Chris Wilson]

If the HW (or driver) doesn't support logical contexts, don't pretend we
gain anything from trying to execute GPU commands with them. At best it
reports -ENODEV, which is an unhelpful failure that we should just skip.
