staging: wfx: improve interface between data_tx.c and queue.c
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
