Bluetooth: Mesh: Allow TTL <= 1 for the local net interface

Johan Hedberg · Anas Nashif · commit 061e8096be4f · 2017-10-19T05:34:48.000-04:00
The bt_mesh_net_relay() function needs to allow TTL &lt;= 1 for the local
network interface since that's the code path that locally originated
outgoing packets take.
