From: Juuso Oikarinen <juuso.oikarinen@xxxxxxxxx> This patch adds to the fix "fix BSS double-unlinking" (commit 3207390a8b58bfc1335750f91cf6783c48ca19ca) by Johannes Berg. It turns out, that the double-unlinking scenario can also occur if expired BSS elements are removed whilst an interface is performing association. To work around that, replace list_del with list_del_init also in the "cfg80211_bss_expire" function, so that the check for whether the BSS still is in the list works correctly in cfg80211_bss_expire.
