e2e: prevent re-using empty pvc object

Browse Source 
When an error occurs, the pvc object is overwritten in the
PollImmediate() loop. Re-using the pvc.Namespace results in error
messages like

    Error getting pvc in namespace: '': an empty namespace may not be set when a resource name is provided

and prevents the retry by PollImmediate() to never succeed. Storing the
namespace in a local variable prevents this from happening.
