    libvirt: continue detach if instance not found

    Currently the libvirt code will always logout of the iscsi target
    during detach error, but the exception will cause the volume to
    remain in an attached state. This needs to be more consistent, so
    This patch checks specifically for not found and logs a warning
    and explicitly detaches. Any other exception will leave iscsi
    logged in and leave the volume in the attached state.

    Fixes bug 1057756
