This caused a regression for hardware using IEEE80211_HW_WANT_MONITOR_VIF. In monitor mode, link->conf->bss is uninitialized, but current logic allows these notifications to reach driver callbacks, causing a deterministic NULL dereference in drivers like iwldvm. Fix this by validating the BSS context before driver notification.
