Subject: [PATCH] can: xilinx_can: remove redundent netif_napi_del from xcan_remove

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:

| drivers/net/can/xilinx_can.c: In function ‘xcan_remove’:
| drivers/net/can/xilinx_can.c:1847:20: error: unused variable ‘priv’ [-Werror=unused-variable]
| 1847 | struct xcan_priv *priv = netdev_priv(ndev);
| | ^~~~

regards,
Marc
