e2e storage: remove WaitForPodTerminatedInNamespace

Browse Source 
Calling WaitForPodTerminatedInNamespace after testFlexVolume is useless because
the client pod that it waits for always gets deleted by testVolumeClient:

0fcc3dbd55/test/e2e/framework/volume/fixtures.go (L541-L546)

Worse, because WaitForPodTerminatedInNamespace treats "not found" as "must keep
polling", these two tests always kept waiting for 5 minutes:

    Kubernetes e2e suite: [It] [sig-storage] Flexvolumes should be mountable
    when non-attachable 	6m4s

The only reason why these tests passed is that WaitForPodTerminatedInNamespace
used to return the "not found" API error. That is not guaranteed and about to
change.
