net: mac802154: Rename the main tx_work struct
This entry is dedicated to synchronous transmissions done by drivers
without async hook. Make this clearer that this is not a work that any
driver can use by at least prefixing it with "sync_". While at it, let's
enhance the comment explaining why we choose one or the other.
