    platform/x86/intel/ifs: Initialize union ifs_status to zero
    
    [ Upstream commit 3114f77e9453daa292ec0906f313a715c69b5943 ]
    
    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.
