icmp: Fix data-races around sysctl_icmp_echo_enable_probe.

While reading sysctl_icmp_echo_enable_probe, it can be changed
concurrently.  Thus, we need to add READ_ONCE() to its readers.

Fixes: 72aea1cc9c46 ("icmp: add response to RFC 8335 PROBE messages")
Fixes: 2f400e428b52 ("ipv6: ICMPV6: add response to ICMPV6 RFC 8335 PROBE messages")
