commit ce04abc3fcc62cd5640af981ebfd7c4dc3bded28 upstream.
When userspace sets basic rates, it might send us some rates
list that's empty or consists of invalid values only. We're
currently ignoring invalid values and then may end up with a
rates bitmap that's empty, which later results in a warning.
Reject the call if there were no valid rates.
[ Conflict resolution involved adjusting the patch to accommodate
changes in the function signature of ieee80211_parse_bitrates and
ieee80211_check_rate_mask ]
