netfilter: ipset: Null pointer exception in ipset list:set
If we use before/after to add an element to an empty list it will cause
a kernel panic.
$> cat crash.restore
create a hash:ip
create b hash:ip
create test list:set timeout 5 size 4
add test b before a
$> ipset -R < crash.restore
Executing the above will crash the kernel.
