ipv6: do not allow ipv6 module to be removed

There was some bug report on ipv6 module removal path before.
Also, as Stephen pointed out, after vxlan module gets ipv6 support,
the ipv6 stub it used is not safe against this module removal either.
So, let's just remove inet6_exit() so that ipv6 module will not be
able to be unloaded.
