[PATCH] Do not retry scan after failure if operating in ap_mode

[pasi.sjoholm at jolla.com]

From: Pasi Sj?holm <pasi.sjoholm at jollamobile.com>

Commit 2d9c99e37b29a639dafa431df38e1586a31ba887 introduced
a regression while running in ap_mode together with ap_scan
configured with value of 2.

Retrying caused following path to be called:
wpa_supplicant_req_scan()->wpa_supplicant_scan()->
wpa_supplicant_assoc_try()->wpa_supplicant_associate()->
wpa_supplicant_create_ap()

Which eventually teared down the currently configured
ap_mode by calling wpa_supplicant_ap_deinit().
