tracing: Convert some ext4 events to DEFINE_TRACE
Use DECLARE_EVENT_CLASS to remove duplicate code:
text data bss dec hex filename
294695 6104 340 301139 49853 fs/ext4/ext4.o.old
289983 6104 324 296411 485db fs/ext4/ext4.o
5 events are convertd:
ext4__write_begin: ext4_write_begin, ext4_da_write_begin
ext4__write_end: ext4_{ordered, writeback, journalled}_write_end
No change in functionality.
