datapath: Return err if default route is not found

Previously, cilium-agent was panicking if no default route was found:

panic: runtime error: index out of range [0] with length 0

    goroutine 1 [running]:
    github.com/cilium/cilium/pkg/datapath/linux/route.lookupDefaultRoute(0xa,
    0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, ...)
            /go/src/github.com/cilium/cilium/pkg/datapath/linux/route/route.go:104
            +0x445

To fix this, return an error instead.
