net: vxlan: lwt: Fix vxlan local traffic.

Browse source 
commit bbec7802c6948c8626b71a4fe31283cb4691c358 upstream.

vxlan driver has bypass for local vxlan traffic, but that
depends on information about all VNIs on local system in
vxlan driver. This is not available in case of LWT.
Therefore following patch disable encap bypass for LWT
vxlan traffic.

Fixes: ee122c79d4 ("vxlan: Flow based tunneling").
