Subject: [PATCH v3 19/41] net: ieee802154: ca8210: Call the complete helper when a transmission is over

ieee802154_xmit_complete() is the right helper to call when a
transmission is over. The fact that it completed or not is not really a
question, but drivers must tell the core that the completion is over,
even if it was canceled. Do not call ieee802154_wake_queue() manually,
in order to let full control of this task to the core.

Here the two paths are equivalent of calling *_xmit_complete() with its
ifs_handling parameter set to true or false, so let's use it instead of
open coding it.
