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).
