2.6.33-stable review patch. If anyone has any objections, please let us know.

------------------

From: Felix Fietkau <nbd(a)openwrt.org>

commit 1144601118507f8b3b676a9a392584d216d3f2cc upstream.

With the enable_radio being uninitialized, ath_radio_enable() might be
called twice, which can leave some hardware in an undefined state.
