nsproxy: use put_nsproxy() in switch_task_namespaces()
We already have a dedicated helper that handles reference count checking so stop open-coding the reference count check in switch_task_namespaces() and use the dedicated put_nsproxy() helper instead. Take the change to fix a whitespace issue too.
