Nicolas Dichtel 0aa47c27f8 ipv4: fix source address selection with route leak 
commit 6807352353561187a718e87204458999dbcbba1b upstream.

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")
