    x86/hvm_event: fix uninitialized struct field usage introduced by c/s 
f5365e6
    
    c/s f5365e6: "xen/vm-events: Move parts of monitor_domctl code to 
common-side",
    introduced a use without initialization issue.
    hvm_event_breakpoint calls hvm_event_traps(&req) and if sync is true that
    ors some bits into req->flags which was never initialised.
    Reported by Coverity Scan.
    
    Initializes req @ hvm_event_breakpoint entry.
