It is false positive reporting based because DeviceLibLowestSupportedVersion will have assigned value after FmpDeviceGetLowestSupportedVersion() returns SUCCESS. This patch refines the code to initialize DeviceLibLowestSupportedVersion to DEFAULT_LOWESTSUPPORTEDVERSION before calling FmpDeviceGetLowestSupportedVersion(). It can pass the static tool's check.
