SME: Fix processing of Authentication timeout and failure

current_bss and pending_bssid weren't cleaned up so BSS
kept appearing in the scan results even when it was actually gone.
Use wpa_supplicant_mark_disassoc() to cleanup the wpa_s context
instead of just dropping wpa_state back to DISCONNECTED.
