    x86/traps: Fix typo in do_entry_CP()
    
    The call to debugger_trap_entry() should pass the correct vector.  The
    break-for-gdbsx logic is in practice unreachable because PV guests can't
    generate #CP, but it will interfere with anyone inserting custom debugging
    into debugger_trap_entry().
    
    Fixes: 5ad05b9c2490 ("x86/traps: Implement #CP handler and extend #PF for 
shadow stacks")
