unnecessary check for None

[huguesv]

In servicebusservice.py and in storageclient.py the function:

def _perform_request(self, request):


does not need to check:

if not resp:
return None


Both functions can be changed to the following:

def _perform_request(self, request):
try:
return self._filter(request)
except HTTPError as e:
return _service_bus_error_handler(e)
