nl80211: Clear ignore_next_local_deauth flag

Browse source 
The de-authentication flow in wpa_driver_nl80211_deauthenticate() can
result in a locally generated de-authentication event. To avoid getting
this extra event ignore_next_local_deauth flag is set, and should be
cleared when the next local deauth event is received. However, it is not
cleared when the event shows up after the wpa_supplicant has started a
connection with a new AP, and as a result it might ignore future
deauth event from the driver.

Fix this by clearing the flag if the event is locally generated.
