wifi: cfg80211: Fix return value in scan logic

The reporter noticed a warning when running iwlwifi:

WARNING: CPU: 8 PID: 659 at mm/page_alloc.c:4453 __alloc_pages+0x329/0x340

As cfg80211_parse_colocated_ap() is not expected to return a negative
value return 0 and not a negative value if cfg80211_calc_short_ssid()
fails.
