rS290630: urtwn(4): refactor and fix TX path.

Summary

Split urtwn_tx_start() into urtwn_tx_data() and urtwn_tx_start() (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 (again).
Add IEEE80211_RADIOTAP_F_WEP flag for encrypted frames.
Check URTWN_RUNNING flag under lock.

This change will greatly simplify subsequent (WME, HOSTAP support) updates.
Note: rate adaptation is not fixed yet.

Test Plan

Tested with RTL8188EU, STA mode.
