Nicolas Dichtel 6807352353 ipv4: fix source address selection with route leak 
By default, an address assigned to the output interface is selected when
the source address is not specified. This is problematic when a route,
configured in a vrf, uses an interface from another vrf (aka route leak).
The original vrf does not own the selected source address.

Let's add a check against the output interface and call the appropriate
function to select the source address.

Fixes: 8cbb512c92 ("net: Add source address lookup op for VRF")
