drm/amd/ras: allow waking RAS processing without an event

Browse source

GPU MCE handling queues bank data directly in the MCE FIFO and only
needs to wake the RAS processing thread. Requiring a separate event
request prevents this path from scheduling processing when no event
object is available.

Permit a NULL request to skip event queue insertion while still
incrementing the interrupt request count and waking the processing
thread.
