iwlwifi: mvm: rs: fix search cycle rules
We should explore all possible columns when searching to be as resilient as possible to changing conditions. This fixes for example a scenario where even after a sudden creation of rssi difference between the 2 antennas we would keep doing MIMO at a low rate instead of switching to SISO at a higher rate using the better antenna which was the optimal configuration.
