* [PATCH] ath9k: Fix symbol overlap window for half/quarter channels

Since commit cd6cfd7311a385144a2f9c74f692ae2df3ae033f
"ath9k: do not set half/quarter channel flags in AR_PHY_MODE" the
condition "rfMode & (AR_PHY_MODE_QUARTER | AR_PHY_MODE_HALF)" would
never evaluate to true.

Fix this by using the available IS_CHAN_HALF_RATE and IS_CHAN_QUARTER_RATE
marcros instead.

Just stumbled over that piece of code while looking into TX99, so
this is only compile-tested.

Felix, can you please confirm if this is correct or if removing
the whole block would be better?

Thanks,
Helmut
