soc: qcom: rpmh-rsc: Include state in trace event

When tracing messages written to the RSC it's very useful to know the
type of TCS being targeted, in particular if/when the code borrows a
WAKE TCS for ACTIVE votes.

Add the "state" of the message to the traced information.

While at it, drop the "send-msg:" substring, as this is already captured
by the trace event itself.

soc: qcom: rpmh-rsc: Avoid unnecessary checks on irq-done response

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.
