ftrace: Avoid crashing if format doesn't match expectations
Kernel commit 0b04d4c0542e("f2fs: Fix f2fs_truncate_partial_nodes ftrace
event") changed the format of an event in a way that causes perfetto to
hit a PERFETTO_FATAL.
The PERFETTO_FATAL was probably not intentional there, it was added
(probably by mistake) by 6db99a9ca272("Add PERFETTO_DFATAL.").
In any case, perfetto shouldn't crash for an event it doesn't
understand.
