ionic: start watchdog after all is setup

ionic: start watchdog after all is setup

[ Upstream commit 9ad2939a1525962a79a2fd974ec7e3a71455b964 ]

The watchdog expects the lif to fully exist when it goes off,
so lets not start the watchdog until all is ready in case there
is some quirky time dialation that makes probe take multiple
seconds.
