Oscar Maes 018afe914b net: ipv4: fix regression in local-broadcast routes
[ Upstream commit 5189446ba995556eaa3755a6e875bc06675b88bd ]

Commit 9e30ecf23b ("net: ipv4: fix incorrect MTU in broadcast routes")
introduced a regression where local-broadcast packets would have their
gateway set in __mkroute_output, which was caused by fi = NULL being
removed.

Fix this by resetting the fib_info for local-broadcast packets. This
preserves the intended changes for directed-broadcast packets.
