Subject: [PATCH] can: ctucanfd: Remove a useless netif_napi_del() call

free_candev() already calls netif_napi_del(), so there is no need to call
it explicitly. It is harmless, but useless.

This makes the code mode consistent with the error handling path of
ctucan_probe_common().

While at it, remove a wrong comment about the return value of this
function.
