[PATCH 5.15 14/92] wifi: cfg80211: Fix return value in scan logic

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Ilan Peer <ilan.peer@intel.com>

[ Upstream commit fd7f08d92fcd7cc3eca0dd6c853f722a4c6176df ]

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.

Fixes: c8cb5b854b40f ("nl80211/cfg80211: support 6 GHz scanning")
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217675
