In case AP sends disassociate to sta wpa_supplicant generates a deauthenticate
event to clear driver state and also turns on the ignore_next_local_deauth flag
expecting to get a deauth event for a locally generated deauth.
However, no deauth or disconnect events are received, since sta is already
marked as disconnected.
AP will connect to AP2 (the new AP) but if connection to AP2 is lost deauth
event to wpa_supplicant will be ignored since the ignore_next_local_deauth
was never set to 0. So wpa_supplicant is unaware that station is disconnected
and does not initiate scan.
Fix: Set ignore_next_local_deauth flag to 0 upon connection
