cfg80211: fix cfg80211_beacon_dup
commit bee92d06157fc39d5d7836a061c7d41289a55797 upstream.
gcc-8 warns about some obviously incorrect code:
net/mac80211/cfg.c: In function 'cfg80211_beacon_dup':
net/mac80211/cfg.c:2896:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict]
From the context, I conclude that we want to copy from beacon into
new_beacon, as we do in the rest of the function.
Cc: stable@vger.kernel.org
Fixes: 73da7d5bab79 ("mac80211: add channel switch command and beacon callbacks")
