[TS-3235] fix crash problem caused by sync problem in PluginVC.
This fix is for the multi-thread sync problem exists in PluginVC of TS-3235.
Below is the scenario of this problem:
1. customer uses interceptplugin which calls TSVIOReenable and TSVConnClose
and that will call PluginVC's APIs in their work threads
2. That customer creates their work threads by using TSThreadCreate which
are not controlled by ATS.
3. Because the interceptplugin works in their work threads and the lock
provided by interceptplugin can only sync their work threads and it cannot sync
the threads between ATS and interceptplugin, the sync problem will occur when
TSVIOReenable and TSVConnClose are called from intercetplugin in customer's
work threads.
So, we need to consider this kind of scenario also, as it is common to
customer to start their threads.
