    remove non-POSIX error codes

    Xen was using some non-POSIX error codes that are removed in this patch. For
    future reference, the list of POSIX error codes has been obtained from:

    http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/errno.h.html

    The error codes already present and defined as optional (XSR), have been
    left in place.
