    x86/EFI: permit setting variable with non-zero attributes
    
    This must have been a copy-and-paste mistake - get_variable uses
    op->misc as output only, and wants to make sure it's zero for future
    extensibility. For set_variable, this is an input though, and hence
    the check is wrong.
