iwlwifi: mvm: fix an overflow in iwl_mvm_get_signal_strength

Browse source

The idea here is to translate a value of 0 received from
the firmware to the lowest rssi figure. As rx_status->chain_signal
is a signed byte the lowest possible value is -128 and not -256.
-256 was causing 0 to get stored in the signed byte.
