[PATCH 5.7 057/166] nl80211: fix memory leak when parsing NL80211_ATTR_HE_BSS_COLOR

[Greg Kroah-Hartman]

From: Luca Coelho <luciano.coe...@intel.com>

[ Upstream commit 60a0121f8fa64b0f4297aa6fef8207500483a874 ]

If there is an error when parsing the NL80211_ATTR_HE_BSS_COLOR
attribute, we return immediately without freeing param.acl.  Fit it by
using goto out instead of returning immediately.

Fixes: 5c5e52d1bb96 ("nl80211: add handling for BSS color")
