hw_breakpoints: Fix percpu build failure

Fix this build error:

   kernel/hw_breakpoint.c:58:1: error: pasting "__pcpu_scope_" and "*" does not give a valid preprocessing token

It happens if CONFIG_DEBUG_FORCE_WEAK_PER_CPU, because we concatenate
someting with the name and we have the "*" in the name.
