netdevsim: fix backwards compatibility in nsim_get_iflink()
The default ndo_get_iflink() implementation returns the current ifindex
of the netdev. But the overridden nsim_get_iflink() returns 0 if the
current nsim is not linked, breaking backwards compatibility for
userspace that depend on this behaviour.
Fix the problem by returning the current ifindex if not linked to a
peer.
