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
