#2110: Incorrect use of sc->sc_dfs_cac_timer.data

It appears that some DFS code is never executed because a comparison
is always wrong.
Both in the trunk and the DFS branch, sc->sc_dfs_cac_timer.data is set
to sc in ath_attach(), but ath_newstate() compares it to vap. Those
variables are pointers to struct ath_softc and struct ieee80211vap
respectively. They cannot legitimately point to the same address in
memory, thus the condition is always false.
The 0.9.4 branch has that code as well, except that the variable is called
sc->sc_dfswaittimer.data
The code is very old. It was present in the original import of
madwifi-ng (revision 1175).
