tracing: Annotate event field-defining functions with __init
Those functions are called either during kernel boot or module init.
Before:
$ dmesg | grep 'Freeing unused kernel memory'
Freeing unused kernel memory: 1208k freed
Freeing unused kernel memory: 1360k freed
Freeing unused kernel memory: 1960k freed
After:
$ dmesg | grep 'Freeing unused kernel memory'
Freeing unused kernel memory: 1236k freed
Freeing unused kernel memory: 1388k freed
Freeing unused kernel memory: 1960k freed
