i3c: master: svc: wait for Manual ACK/NACK Done before next step

Wait for the controller to complete emitting ACK/NACK, otherwise the next
command may be omitted by the hardware.

Add a "command done" check in svc_i3c_master_nack(ack)_ibi() and change the
return type to int to flag possible timeouts.
