iwlwifi: fix wrong WGDS_WIFI_DATA_SIZE

From coreboot/BIOS:
Name ("WGDS", Package() {
 Revision,
 Package() {
     DomainType,                         // 0x7:WiFi ==> We miss this one.
     WgdsWiFiSarDeltaGroup1PowerMax1,    // Group 1 FCC 2400 Max
     WgdsWiFiSarDeltaGroup1PowerChainA1, // Group 1 FCC 2400 A Offset
     WgdsWiFiSarDeltaGroup1PowerChainB1, // Group 1 FCC 2400 B Offset
     WgdsWiFiSarDeltaGroup1PowerMax2,    // Group 1 FCC 5200 Max
     WgdsWiFiSarDeltaGroup1PowerChainA2, // Group 1 FCC 5200 A Offset
     WgdsWiFiSarDeltaGroup1PowerChainB2, // Group 1 FCC 5200 B Offset
     WgdsWiFiSarDeltaGroup2PowerMax1,    // Group 2 EC Jap 2400 Max
     WgdsWiFiSarDeltaGroup2PowerChainA1, // Group 2 EC Jap 2400 A Offset
     WgdsWiFiSarDeltaGroup2PowerChainB1, // Group 2 EC Jap 2400 B Offset
     WgdsWiFiSarDeltaGroup2PowerMax2,    // Group 2 EC Jap 5200 Max
     WgdsWiFiSarDeltaGroup2PowerChainA2, // Group 2 EC Jap 5200 A Offset
     WgdsWiFiSarDeltaGroup2PowerChainB2, // Group 2 EC Jap 5200 B Offset
     WgdsWiFiSarDeltaGroup3PowerMax1,    // Group 3 ROW 2400 Max
     WgdsWiFiSarDeltaGroup3PowerChainA1, // Group 3 ROW 2400 A Offset
     WgdsWiFiSarDeltaGroup3PowerChainB1, // Group 3 ROW 2400 B Offset
     WgdsWiFiSarDeltaGroup3PowerMax2,    // Group 3 ROW 5200 Max
     WgdsWiFiSarDeltaGroup3PowerChainA2, // Group 3 ROW 5200 A Offset
     WgdsWiFiSarDeltaGroup3PowerChainB2, // Group 3 ROW 5200 B Offset
 }
})

When read the ACPI data to find out the WGDS, the DATA_SIZE is never
matched.
From the above format, it gives 19 numbers, but our driver is hardcode
as 18.
Fix it to pass then can parse the data into our wgds table.
Then we will see:
iwlwifi 0000:01:00.0: U iwl_mvm_sar_geo_init Sending GEO_TX_POWER_LIMIT
iwlwifi 0000:01:00.0: U iwl_mvm_sar_geo_init SAR geographic profile[0]
