    xen: fix parsing xend http response
    
    Commit df36af58 broke parsing of http response from xend.  The prior
    use of atoi() would happily parse e.g. a string containing "200 OK\r\n",
    whereas virStrToLong_i() will fail when called with a NULL end_ptr.
    Change the calls to virStrToLong_i() to provide a non-NULL end_ptr.
