nf: qtaguid: make procfs entry for ctrl return correct data.

(This is a direct cherry-pick from 2.6.39: I3b925802)

Fixed procreader for /proc/net/xt_qtaguid/ctrl: it would just
fill the output with the same entry.
Simplify the **start handling.

nf: qtaguid: workaround xt_socket_get_sk() returning bad SKs.

(This is a direct cherry pick from 2.6.39: Id2a9912b)

* xt_socket_get_sk() returns invalid sockets when the sk_state is TCP_TIME_WAIT.
Added detection of time-wait.
* Added more constrained usage: qtaguid insures that xt_socket_get*_sk() is
not invoked for unexpected hooks or protocols (but I have not seen those
active at the point where the returned sk is bad).
