Fix session timeout after ANQP dummy STA entry with SME-in-driver

Upon association, disable the timer that removes the dummy STA. This
timer caused the STA that associates within 5 seconds of doing an ANQP
query to disassociate, thinking it's a dummy STA. Similar call was
already there for the SME/MLME-in-hostapd case in handle_auth(), but the
SME-in-driver case was not previously addressed.
