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, specifically the updated first parameter ]

Hi, I'm resending the backport for v5.15 [1], following the one I previously sent for v6.1 [2].
Now queued up, thanks.
