    sesutil: fix "fault all" with zoned jbods
    
    Some SAS JBODs support zoning.  This feature allows individual SAS
    targets to be accessible by only some initiator ports.  One application
    would be connecting two servers to the same JBOD, but they wouldn't be
    able to see each other's disks.
    
    A zoned JBOD should also prohibit initiators from accessing SES elements
    corresponding to inaccessible SAS targets.  It reports that by setting
    the element's status code to 0x8 (No Access Allowed).
    
    The bug is that when doing "sesutil (fault|locate) all ...", sesutil
    will attempt a ENCIOC_SETELMSTAT ioctl for every single element, even
    the inaccessible ones.  The enclosure will reject the command, the
    kernel will return EINVAL, and sesutil will exit.
    
    The solution is to check the element's status, and skip trying to set it
    if the status is 0x8.  But if the user actually supplied a ses ID, then
    assume that he knows what he's doing and try to set it anyway.
