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.
