After implementing subscription delete feature in e2sim, it was noticed that e2sim was only able receive only single delete request (when sending multiple delete request).​

Issue was in the existing code of e2sim and was related to  socket creation and reuse of the port address.​

Fixed this issue by declaring socket file descriptor as local variable instead of global variable and passed this variable as argument to functions. ​

And commented the functionality of reusing same port address for each e2sim instances.
