[NETLINK] Return err in netlink_connect

[Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>]

Hi:

This patch makes netlink_connect() return the value of err instead of 0.
It doesn't actually make any difference since the current implementation
of netlink_autobind() never fails.  But since we went to all this trouble
to check the return status of autobind, might as well return the correct
value :)
