Subject: [PATCH net-next] ipv4: Set nexthop flags in a more consistent way

From: Ido Schimmel <idosch@...dia.com>

Be more consistent about the way in which the nexthop flags are set and
set them in one go.

RTNH_F_DEAD and RTNH_F_LINKDOWN are set separately above, so I decided
to keep them as-is.
