set_primary_if exchanges the current primary interfaces with a new one.
This is a new reference and thus we have to count it and decrease the
count of the old primary interface.

I would like to keep that order of hold -> exchange -> put for later
changes (rcu or something like that for primary_if and curr_gw).
