Our detector has identified another case of an incomplete policy.
Specifically, the commit df78a0c0b67d ("nl80211: S1G band and channel
definitions") introduced the NL80211_BAND_S1GHZ attribute to
nl80211_band, but it neglected to update the
nl80211_match_band_rssi_policy accordingly.
Similar commits that add new band types, such as the initial
commit 1e1b11b6a111 ("nl80211/cfg80211: Specify band specific min RSSI
thresholds with sched scan"), the commit e548a1c36b11 ("cfg80211: add 6GHz
in code handling array with NUM_NL80211_BANDS entries"), and the
commit 63fa04266629 ("nl80211: Add LC placeholder band definition to
nl80211_band"), all require updates to the policy.
Failure to do so could result in accessing an attribute of unexpected
length in the function nl80211_parse_sched_scan_per_band_rssi.
To resolve this issue, this commit adds the policy for the
NL80211_BAND_S1GHZ attribute.
