icmp: Account for ICMP out errors
When ip_append() fails because of socket limit or memory shortage,
increment ICMP_MIB_OUTERRORS counter, so that "netstat -s" can report
these errors.
LANG=C netstat -s | grep "ICMP messages failed"
0 ICMP messages failed
For IPV6, implement ICMP6_MIB_OUTERRORS counter as well.
# grep Icmp6OutErrors /proc/net/dev_snmp6/*
/proc/net/dev_snmp6/eth0:Icmp6OutErrors 0
/proc/net/dev_snmp6/lo:Icmp6OutErrors 0
