    mini-os/x86-64 entry: remove unnecessary event blocking
    
    We don't need to block events here because:
     - if we came from "hypervisor_callback", events are disabled at this point,
       no need to block again;
     - if we came from "error_entry", we shouldn't touch event mask, for
       exception hanlding are meant to be interrupted by Xen events (virtual
       irq).
