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.
