    Revert "sysctl: return -EINVAL if val violates minmax"
    
    This reverts commit e260ad01f0aa9e96b5386d5cd7184afd949dc457.
    
    Virtuozzo Linux 8 environment (userspace) is not ready for that kind of
    sysctl writes failures, so while we build vz9 as vz8 userspace + vz9
    kernel let's revert this patch.
    
    Will drop this revert once we switch fo vl9 userspace in vz9.
