drm/i915/perf: Validate OA sseu config outside switch
Once OA supports media engine class:instance, the engine can only be
validated outside the switch since class and instance parameters are
separate entities. Since OA sseu config depends on engine
class:instance, validate OA sseu config outside the switch.
v2: (Ashutosh)
- Clarify commit message
- Use drm_dbg instead of DRM_DEBUG
- Reorder stack variables
