    gdbsx_guestmemio: allow it to check domain
    
    gdbsx_guest_mem_io() does not get d passed, it expects to handle the
    domain lookup itself. Specifically, the caller of
    XEN_DOMCTL_gdbsx_guestmemio is expected to use DOMID_IDLE to interact
    with the hypervisor, rather than a domain, which doesn't interact well
    with with the domain rcu lock.
