mesh: Do not clear link state on driver event if exchange was started

Browse source 
If the local driver event for a new peer candidate arrived only after
the peer had already initiated the peering exchange, we used to clear
the link state. This resulted in the already completed (or in progress)
exchange getting abandoned and a new exchange initiated. This is not
desirable since the already started (or even completed) exchange can be
used. Clear the link state only when adding the new STA entry for the
first time, i.e., use the same !sta->my_lid condition in handling the
driver event similarly to how the peer initiated cases were already
handled.
