x86/traps: Fix typo in do_entry_CP()

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().
