platform/x86/intel/ifs: Initialize union ifs_status to zero
[ Upstream commit3114f77e94
] If the IFS scan test exits prematurely due to a timeout before completing a single run, the union ifs_status remains uninitialized, leading to incorrect test status reporting. To prevent this, always initialize the union ifs_status to zero. Fixes:2b40e654b7
