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.
