nl80211: Clear ignore_next_local_deauth and ignore_deauth_event

The authentication flow in wpa_driver_nl80211_authenticate() can
result  in a locally generated de-authentication, in which both
next_local_deauth and ignore_next_local_deauth are set.

However, in mlme_event_deauth_disassoc(), when ignore_deauth_event is
set, the flag is cleared, but the flow immediately returns leaving
ignore_next_local_deauth set, which can result in ignoring future deauth
event from the driver, leaving the wpa_supplicant in an inconsistent
state.

Fix this by clearing both flags in case that next_local_deauth is set.
