Merge patch series "can: rx-offload: fix order of unregistration calls"

Marc Kleine-Budde <mkl@pengutronix.de> says:

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.

With the mcp251xfd driver the removal of the module causes the
following warning:

| WARNING: CPU: 0 PID: 352 at net/core/dev.c:7342 __netif_napi_del_locked+0xc8/0xd8

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().

All other driver using the rx-offload helper have been checked and the
same issue has been found in the rockchip and m_can driver. These have
been fixed, but only compile time tested. On the mcp251xfd the fix was
tested on hardware.
