In atw_init(), always call atw_write_wep() to write the WEP state 

to the h/w.  This prevents a spurious call to atw_write_wep() later,
in IEEE80211_S_RUN state, when net80211 times-out ieee80211_nodes.
It is important to avoid a spurious atw_write_wep() call because
in IBSS mode, at least, WEP re-initialization reliably locks up
the transmitter.

XXX There must be a bug in atw_write_wep() that causes it to lock
XXX up the transmitter.  I will revisit it later.
