Subject: [ 37/89] ath9k: remove the WARN_ON that triggers if generating a beacon fails

3.7-stable review patch.  If anyone has any objections, please let me know.

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

From: Felix Fietkau <nbd@...nwrt.org>

commit 3adcf20afb585993ffee24de36d1975f6b26b120 upstream.

During teardown, mac80211 will not return a new beacon. This is normal and
handled properly in the driver, so there's no need to spam the user with a kernel
warning here.
