    can: m_can: disable_all_interrupts, not clear active_interrupts
    
    [ Upstream commit a572fea86c9b06cd3e6e89d79d565b52cb7e7cff ]
    
    active_interrupts is a cache for the enabled interrupts and not the
    global masking of interrupts. Do not clear this variable otherwise we
    may loose the state of the interrupts.
