urtwn(4): refactor and fix TX path.

- Split urtwn_tx_start() into urtwn_tx_data() and urtwn_tx_start()
  (the last will be used for beacon updates / raw xmit path).
- Remove unneeded code from _urtwn_getbuf().
- Use CCK11 for data frames in 11b mode.
- Send EAPOL frames at 1 Mbps.
- Reduce code duplication in urtwn_tx_data().
- Fix sequence numbering.
- Add IEEE80211_RADIOTAP_F_WEP flag for encrypted frames.
- Check URTWN_RUNNING flag under lock.

Tested with RTL8188EU, STA mode.
