can: mcan: m_can_class_unregister(): fix order of unregistration calls

If a driver is removed, the driver framework invokes the driver's
remove callback. A CAN driver's remove function calls
unregister_candev(), which calls net_device_ops::ndo_stop further down
in the call stack for interfaces which are in the "up" state.

The removal of the module causes a warning, as can_rx_offload_del()
deletes the NAPI, while it is still active, because the interface is
still up.

To fix the warning, first unregister the network interface, which
calls net_device_ops::ndo_stop, which disables the NAPI, and then call
can_rx_offload_del().
