The move from ip4(6)_src_address_for_packet to fib_sas4(6)_get changed
the behavior, so that the new looked only to adjacent gleans. This
caused a problem for destinations routed according to FIB table.
To reproduce:
vpp# create tap
vpp# set interface state tap0 up
vpp# set interface ip address tap0 192.168.11.1/24
vpp# ip route add 192.168.20.0/24 via 192.168.11.2
linux$ sudo ip addr add 192.168.20.1/24 dev lo
linux$ sudo ip link set tap0 up
linux$ sudo ip addr add 192.168.11.2/24 dev tap0
vpp# ping 192.168.20.1
Failed: no source address for egress interface
