dhcpv4: Fix a panic in parsing of route options
When parsing a route option with a mask size >32, there would be a panic
at option_routes.go:47 as user-supplied data is used without
verification for a slice bound, causing a read of masksize/8, whic is
possibly >4 bytes. Instead reject the invalid route
