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.
