staging: wfx: simplify handling of IEEE80211_TX_CTL_SEND_AFTER_DTIM
When mac80211 ask for a frame to be sent after a DTIM, driver should:
1. Update TIM with multicast bit set (using update_ie). This function
can be called whenever.
2. Keep buffered all frames marked "after dtim"
3. When it receive a suspend_resume indication (see
wfx_suspend_resume_mc()), send all the buffered frames. This
indication is sent by the firmware 4ms before the dtim.
4. If one of the frames returns status "REQUEUE", it means that the
DTIM period was ended before to be able to send the frame.
5. When all the buffered frames were sent or if DTIM period was ended,
driver should update the TIM with multicast bit reset.
All the mess with the asynchronous works can be dropped.
