fib: fix the drop counter for ipv6 RPF failures
Type: fix the only change to the mfib forwarding node is to set the error code, the rest is checkstyle formatting. The traces previously showed some bogus reason: 00:04:27:325550: ip6-mfib-forward-rpf entry 10 itf -1 flags 00:04:27:325551: ip6-drop fib:0 adj:10 flow:0 UDP: fe80::b203:eaff:fe02:604 -> ff02::1:2 tos 0x00, flow label 0x651ed, hop limit 1, payload length 64 UDP: 546 -> 547 length 64, checksum 0xec9a 00:04:27:325551: error-drop rx:GigabitEthernet6/0/0 00:04:27:325553: drop ip6-input: drops due to concurrent reassemblies limit Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I294684c36edc346b4ebdd83ba66888b3b2197704
