tracing: Convert more ext4 events to DEFINE_EVENT 

Use DECLARE_EVENT_CLASS, and save ~2.7K:

   text    data     bss     dec     hex filename
 274441    7200     260  281901   44d2d fs/ext4/ext4.o.orig
 271881    7040     256  279177   44289 fs/ext4/ext4.o

4 events are converted:

  ext4__mb_new_pa: ext4_mb_new_inode_pa, ext4_mb_new_group_pa
  ext4__mballoc:   ext4_mballoc_discard, ext4_mballoc_free

No change in functionality.
