NetApp 7mode DOT API error when cleaning image cache

[Tom Barron]

We sometimes see:

                              NetApp API failed. Reason - 13114:
         No actual-pathname for 10.1.0.9:/vol/share_whatever

with Kilo code and NetApp 7mode backend.

The issue is due to our cinder driver passing the entire share to the relevant API instead of just the export path portion of the share.

    Fix 'no actual-pathname' NetApp API error

    Cinder volume logs sometimes show this error

          NetApp API failed. Reason - 13114:
          No actual-pathname for 10.1.0.9:/vol/whatever

    with Kilo code and 7-mode DOT system.

    The issue is due to our Cinder driver passing the
    entire share to the relevant API instead of just
    the export path portion of the share. This only
    happens when the NFS image cache is full, and cached
    files need to be removed.
