server: Treat non-default route as host route

When constructing ip route command in addRouteWithMetric,
we used to check whether the given route is a host route.
In some cases, the isHostRoute() check can return false for
non-default routes. To make this check more foolproof,
check whether a route is non-default in order to treat it
as a host route.

Bluetooth: Fix to avoid framework reboot during monkey.

A case where monkey is running & sometimes framework is
disconnected due to unhandled java Exception during the
unbinding of HID device service on unsuccessful unbinding.
Handling java Illegal Argument exception while unbinding
HID device service solves this issue.
