Under high CAN-bus load the struct net_device_ops::{open,stop}
callbacks (m_can_open(), m_can_close()) don't properly start and
shutdown the device.
Fix the problems by re-arranging the order of functions in
m_can_open() and m_can_close().

Hello,
I've taken Jake's patch and split the timestamp wraparound changes
into separate patch. For now, I've added a Not-Signed-off-by, until
Jake gives the S-o-b.
regards,
Marc
