tracing: Remove __init from __trace_early_add_new_event()

The commit 720dee5 ("tracing/boot: Initialize per-instance event
list in early boot") removes __init from __trace_early_add_events()
but __trace_early_add_new_event() still has __init and will cause a
section mismatch.

Remove __init from __trace_early_add_new_event() as same as
__trace_early_add_events().
