do not show loading image for "shelved offloaded" status

[Masco]

When we shelve an instance via CLI,
in horizon instance table, the 'loading' image is continuously showing in the status column.

This bug is already reported and fixed in bug #1318558 but it is not fixed properly.
for rescue it is working fine but not for shelved offloaded.

    Not display loading image for shelved instances

    If, any of the instances are shelved through CLI
    those instances status are displayed as shelved offloaded
    with a loading image.
    Displaying the loading image for this status are not correct.
    Displaying the loading image is removed for
    the shelved offloaded status.
    This problem is reported and fixed in #1318558 but this fix is
    working only for rescue not for shelved offloaded.
    Now it is fixed for shelved offloaded also.
