iwlwifi: mvm: refactor wowlan and netdetect configuration when suspending
We need to send a WOWLAN_CONFIGURATION command also for netdetect and
configure the rfkill release trigger if needed. To do so, refactor
the code that configures wowlan and netdetect when suspending and send
the WOWLAN_CONFIGURATION command also for net_detect.
