x86/domctl: improve XEN_DOMCTL_hypercall_init error handling

EACCES cannot be distinguished against an incorrect DOMCTL_INTERFACE_VERSION,
and will cause an incorrect "need to rebuild the user-space tool set?" message
from libxc.

On the libxc side, put the useful piece of information in the error message,
rathe than the -1 from do_domctl().
