Chenbo Feng 182e12b8af ANDROID: Add untag hacks to inet_release function 
To prevent protential risk of memory leak caused by closing socket with
out untag it from qtaguid module, the qtaguid module now do not hold any
socket file reference count. Instead, it will increase the sk_refcnt of
the sk struct to prevent a reuse of the socket pointer.  And when a socket
is released. It will delete the tag if the socket is previously tagged so
no more resources is held by xt_qtaguid moudle. A flag is added to the untag
process to prevent possible kernel crash caused by fail to delete
corresponding socket_tag_entry list.
Bug: 36374484
Test: compile and run test under system/extra/test/iptables,
      run cts -m CtsNetTestCases -t android.net.cts.SocketRefCntTest
