nl80211: Fix possible Spectre-v1 for CQM RSSI thresholds

Use array_index_nospec() to sanitize i with respect to speculation.

Note that the user doesn't control i directly, but can make it out
of bounds by not finding a threshold in the array.

[add note about user control, as explained by Masashi]
