Nicolas Dichtel b317d53680 nh: fix scope used to find saddr when adding non gw nh
[ Upstream commit bac0f937c3 ]

As explained by Julian, fib_nh_scope is related to fib_nh_gw4, but
fib_info_update_nhc_saddr() needs the scope of the route, which is
the scope "before" fib_nh_scope, ie fib_nh_scope - 1.

This patch fixes the problem described in commit 747c143072 ("ip: fix
dflt addr selection for connected nexthop").

Fixes: 597cfe4fc3 ("nexthop: Add support for IPv4 nexthops")
