The snmp walk of the zebra rib was skipping entries because in_addr_cmp was replaced with a prefix_cmp which worked slightly differently causing parts of the zebra rib tree to be skipped. Signed-off-by: Donald Sharp <sharpd@nvidia.com> (cherry picked from commit ecd9d44)

Report the routes metric in IPFORWARDMETRIC1 and return
-1 for the other metrics as required by the IP-FORWARD-MIB.
inetCidrRouteMetric2 OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"An alternate routing metric for this route. The
semantics of this metric are determined by the routing-
protocol specified in the route's inetCidrRouteProto
value. If this metric is not used, its value should be
set to -1."
DEFVAL { -1 }
::= { inetCidrRouteEntry 13 }
I've included metric2 but it's the same for all of them.

Was playing with snmp and noticed some issues with zebra's implementation of it.
a) snmp walk was wrong. Whomever wrote this found a new and interesting way to make something simple hard. Further work should be done to optimize this, just putting this back into working order since I broke it in 2019
b) Who would think to walk the individual bytes of a struct to set them to 0 in a loop when memset is available?
c) Metrics are not being reported at all. Let's return them
d) Some missing proto translations. The values are weird so we don't get everything.
