tracing: Convert some jbd2 events to DEFINE_EVENT 

Use DECLARE_EVENT_CLASS to remove duplicate code:

   text    data     bss     dec     hex filename
  34903    1693     448   37044    90b4 fs/jbd2/journal.o.old
  31931    1693     416   34040    84f8 fs/jbd2/journal.o

Four events are converted:

  jbd2_commit: jbd2_start_commit,
               jbd2_commit_{locking, flushing, logging}

No change in functionality.
