[PATCH net 09/10] ovpn: ensure TCP vars are initialized first

[Antonio Quartulli <antonio@openvpn.net>]

Netlink calls may access TCP global vars (i.e. when attaching
a TCP socket), therefore we need to make sure the
latters are initialized beforehand.

For this reason move the global TCP initialization at the top
of the module init function.

Fixes: 11851cbd60ea ("ovpn: implement TCP transport")
