The previous commit dd3e4fc75b4a ("nl80211/cfg80211: add BSS color to NDP ranging parameters") adds a parameter for NDP ranging by introducing a new attribute type named NL80211_PMSR_FTM_REQ_ATTR_BSS_COLOR. However, the author forgot to also describe the nla_policy at nl80211_pmsr_ftm_req_attr_policy (net/wireless/nl80211.c). Just complement it to avoid malformed attribute that causes out-of-attribute access.
