wifi: iwlwifi: disable HE ER mode
HE ER mode (~3 Mbps) provides marginal range benefit over legacy rates,
while effective coverage remains constrained by beacon reception. In
addition, ~3 Mbps is insufficient for laptop connectivity.
Furthermore, any range benefit in 5 and 6 GHz is more easily achieved
by roaming to 2.4 GHz, while avoiding degrading 5 and 6 GHz aggregate
network capacity with low-rate links. Therefore, disable HE ER mode.
