ipv4: icmp: Pass full DS field to ip_route_input() 



Align the ICMP code to other callers of ip_route_input() and pass the
full DS field. In the future this will allow us to perform a route
lookup according to the full DSCP value.

No functional changes intended since the upper DSCP bits are masked when
comparing against the TOS selectors in FIB rules and routes.
