From: Michael Lo michael.lo@mediatek.com

Update the destination index to use 'n_ssids', which is incremented only when a valid SSID is present. Previously, both mt76_connac_mcu_hw_scan() and mt7925_mcu_hw_scan() used the loop index 'i' for the destination array, potentially leaving gaps if any source SSIDs had zero length.
