drivers: modem: modem_cmd_handler: prefer currently assigned handler

[chris-schra]

sorry, @mike-scott for spamming here regarding the driver ;)

I'm creating a driver which assigns URC handlers (for example) for +CREG. But during the init process, I issue AT+CREG? manually to check the current status. If modem is disconnected, I'll connect it, otherwise I'll skip the connection part of the init process. Currently, the order in which handlers are processed is

• response handlers[0]
• unsolicited handlers[1]
• current assigned handlers[2]

But because my URC handlers don't give the sem, the code will never return from the AT+CREG?'s response. So I suggest to reverse the order, processing the currently assigned handlers first. TBH, the ideal order would be Currently assigned handlers -> Response handlers -> Unsolicited handlers But I think there will be no conflicts between unsolicited and response handlers in real world cases.
