From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Currently, wfx_pending_remove() (from queue.c) call wfx_skb_dtor()
(from data_tx.c) that forward the tx status to mac80211.

Moreover, there no purpose to retrieve a frame from the pending queue
without dequeuing it. So, the main purpose of wfx_pending_remove() is to
forward the tx status to mac80211.

Let's make the architecture cleaner:
  - merge wfx_pending_remove() into wfx_pending_get()
  - call wfx_skb_dtor() from data_tx.c
