net: mac802154: Follow the count of ongoing transmissions
In order to create a synchronous API for MLME command purposes, we need
to be able to track the end of the ongoing transmissions. Let's
introduce an atomic variable which is incremented when a transmission
starts and decremented when relevant so that we know at any moment
whether there is an ongoing transmission.
The counter gets decremented in the following situations:
- The operation is asynchronous and there was a failure during the
offloading process.
- The operation is synchronous and the synchronous operation failed.
- The operation finished, either successfully or not.
