Make empty have static storage duration (like net/sysctl_net.c does) to
avoid a potential use-after-return and keep consistent with
__register_sysctl_table @table 'should not be free'd after registration'.
Fixes: 73dbd8cf7947 ("net: Remove ctl_table sentinel elements from several networking subsystems")
