netdev: fix double-free in netdev_nl_bind_rx_doit()

In the Linux kernel, the following vulnerability has been resolved:

netdev: fix double-free in netdev_nl_bind_rx_doit()

Sashiko flags that genlmsg_reply() always consumes the skb.
The error path calls nlmsg_free(rsp) so we can't jump directly
to it. Let's not unbind, just propagate the error to the user.
This is the typical way of handling genlmsg_reply() failures.
They shouldn't happen unless user does something silly like
calling the kernel with an already-full rcvbuf.
