From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>
Since IWL_FW_CMD_VER_UNKNOWN = 99, then my change to consider
cmd_ver >= 7 instead of cmd_ver = 7 included also firmwares that don't
advertise the command version at all. This made us send a command with a
bad size and because of that, the firmware hit a BAD_COMMAND immediately
after handling the REDUCE_TX_POWER_CMD command.
Fixes: 8f892e225f41 ("wifi: iwlwifi: mvm: support iwl_dev_tx_power_cmd_v8")
