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).
