    replace non-POSIX error codes

    Some DOMCTLs returned non-POSIX error codes, replace them with POSIX
    compilant values instead. EBADRQC and EBADSLT are replaced by EDOM, while
    EUSERS is replaced with EOVERFLOW.

    Signed-off-by: Roger Pau Monné <roger.pau@xxxxxxxxxx>

    Replace two EDOM uses.
