Set socket options in correct way

[Abhishek Kekane]

Currently socket options, socket.SO_REUSEADDR and socket.SO_KEEPALIVE
are set only if SSL is enabled.
Ref: https://github.com/openstack/cinder/blob/master/cinder/wsgi.py#L209

The above socket options should be set no matter SSL is enabled or not.

This issue is introduced in patch https://review.openstack.org/#/c/106377/
