The RSC interrupt is issued only after the request is complete. For fire-n-forget requests, the irq-done interrupt is sent after issuing the RPMH request and for response-required request, the interrupt is triggered only after all the requests are complete. These unnecessary checks in the interrupt handler issues AHB reads from a critical path. Lets remove them and clean up error handling in rpmh_request data structures.
