** [tickets:#1521] ntf: Calling saNtfFinalize() parallely with Allocate() or
Unsubscrbe() may lead to deadlock.**

Currently observed between saNtfFinalize() with saNtfNotificationUnsubscribe ()
and also with saNtfStateChangeNotificationAllocate().
Generally any API called after finalize returns with BAD_HANDLE.
But some times finalize() hangs when it is timed in between the processing of
Allocate() or Unsubscribe() as some resources will be in use in these APIs.
1) bt1 between Finalize() and Allocate:
