vpp-swan: change flow in function for add route

This patch addresses the issue when the list of available interfaces is not up to date. Due to this issue adding a new route fails and finally the connection is not established. Type: fix Signed-off-by: Gabriel Oginski <gabrielx.oginski@intel.com> Change-Id: I3a63c0dd99ebc28ea149b4b23867440937682761
