tracing/events: put TP_fast_assign into braces
Currently TP_fast_assign has a limitation that we can't define local
variables in it.
Here's one use case when we introduce __dynamic_array():
TP_fast_assign(
type *p = __get_dynamic_array(item);
foo(p);
bar(p);
),
[ Impact: allow defining local variables in TP_fast_assign ]
