wifi: iwlwifi: mvm: validate SAR GEO response payload size

Browse source

The SAR GEO command response is cast to
iwl_geo_tx_power_profiles_resp without verifying the payload length.
A malformed or unexpected firmware response can lead to reading an
invalid structure layout.

Add an explicit size check before accessing the response data and
return -EIO when the payload size is wrong.
