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")
