drm/i915: Only allocate preempt context when required
If we remove some hardcoded assumptions about the preempt context having
a fixed id, reserved from use by normal user contexts, we may only
allocate the i915_gem_context when required. Then the subsequent
decisions on using preemption reduce to having the preempt context
available.
v2: Include an assert that we don't allocate the preempt context twice.
