tracing: Convert module refcnt events to DEFINE_EVENT 

Use DECLARE_EVENT_CLASS to remove duplicate code:

   text    data     bss     dec     hex filename
  29854    1980     128   31962    7cda kernel/module.o.old
  28750    1980     128   30858    788a kernel/module.o

Two events are converted:

  module_refcnt: module_get, module_put

No change in functionality.
