ipv4: Validate route entry type at insert instead of every lookup.
fib_semantic_match() requires that if the type doesn't signal an
automatic error, it must be of type RTN_UNICAST, RTN_LOCAL,
RTN_BROADCAST, RTN_ANYCAST, or RTN_MULTICAST.
Checking this every route lookup is pointless work.
Instead validate it during route insertion, via fib_create_info().
Also, there was nothing making sure the type value was less than
RTN_MAX, so add that missing check while we're here.
