mlxsw: spectrum_router: Adjust IPv6 replace logic to new notifications
Previously, IPv6 replace notifications were only sent from
fib6_add_rt2node(). The function only emitted such notifications if a
route actually replaced another route.
A previous patch added another call site in ip6_route_multipath_add()
from which such notification can be emitted even if a route was merely
added and did not replace another route.
Adjust the driver to take this into account and potentially set the
'replace' flag to 'false' if the notified route did not replace an
existing route.
