    Ensure that lun_id is an int

    The map_vol_to_host function was treating the lun number
    as a string rather than an int. This was causing attempts
    to mount storwize_svc volumes to Hyper-V nodes to fail as they
    were checking an integer type against a unicode type which
    would fail.

    This change casts result_lun to an integer after the value has
    gone through the ssh injection attack check. This way Hyper-V
    is able to verify if the found LUN is the target LUN, enabling
    mount of storwize_svc volumes to Hyper-V.
