From: Luciano Coelho <luciano.coelho@intel.com>

The call to cfg80211_ch_switch_notify() should be at the end of the
ieee80211_chswitch_post_beacon() function, because it should only be
sent if everything succeeded.

Fixes: d04b5ac9e70b ("cfg80211/mac80211: allow any interface to send channel switch notifications")
