Masashi Honma 4dae18fe79 nl80211: Fix possible Spectre-v1 for CQM RSSI thresholds
commit 4b2c5a14cd8005a900075f7dfec87473c6ee66fb upstream.

commit 1222a1601488 ("nl80211: Fix possible Spectre-v1 for CQM
RSSI thresholds") was incomplete and requires one more fix to
prevent accessing to rssi_thresholds[n] because user can control
rssi_thresholds[i] values to make i reach to n. For example,
rssi_thresholds = {-400, -300, -200, -100} when last is -34.
