netfilter: flowtable: fix missing FLOWI_FLAG_ANYSRC flag

The nf_flow_table gets route through ip_route_output_key. If the saddr
is not local one, then FLOWI_FLAG_ANYSRC flag should be set. Without
this flag, the route lookup for other_dst will fail.

Fixes: 3412e164 (netfilter: flowtable: nft_flow_route use more data for reverse route)
