device: add an initializer

Browse source 
Basically to silence gcc that is not smart enough to understand how does
.initialized and .value relate.

  src/devices/nm-device.c: In function '_commit_mtu':
  src/devices/nm-device.c:6754:15: error: 'ip6_mtu_sysctl.value' may be used uninitialized in this function [-Werror=maybe-uninitialized]
     if (ip6_mtu && ip6_mtu != _IP6_MTU_SYS ()) {
                 ^
