ip: Fix data-races around sysctl_ip_prot_sock.
[ Upstream commit 9b55c20f ] sysctl_ip_prot_sock is accessed concurrently, and there is always a chance of data-race. So, all readers and writers need some basic protection to avoid load/store-tearing. Fixes: 4548b683 ("Introduce a sysctl that modifies the value of PROT_SOCK.")
