    Fix inability to delete volumes in error state for NetApp driver

    While using NetApp 7-mode storage box to create volumes, if the volume
    is not created on the storage box (possibly due to wrong/missing
    options in cinder.conf file), the volume goes in error state, and when
    one tries to delete the volume, an exception was raised which made
    the volume go in error_deleting state, which is unrecoverable. This
    commit quiesces that exception, resulting in successful removal of the
    volume entry from the volume table.

    Fixes bug 1090167
