Since netif_napi_del is already done in the free_candev, so we remove
this redundent netif_napi_del invocation. In addition, this patch can
match the operations in the xcan_probe and xcan_remove functions.

Fixed the following error:

For now, xilinx_can already enables "-Werror" proposed by Linus?

That's my problem. Sorry for that.

Marc
