Alan Brady 16576a034c ping: support ipv6 ping socket flow labels
Ping sockets don't appear to make any attempt to preserve flow labels
created and set by userspace using IPV6_FLOWINFO_SEND. Instead they are
clobbered by autolabels (if enabled) or zero.

Grab the flowlabel out of the msghdr similar to how rawv6_sendmsg does
it and move the memset up so it doesn't get zeroed after.
