print_max and use_max_tr in struct tracer are "int" variables and
used like flags. This is wasteful, so change the type to "bool".

Hi, Steven,
Thank you for your review.
I changed the function name "resize_buffer_even" to
"resize_buffer_duplicate_size".

__tracing_resize_ring_buffer() can be used for (1), and had
implemented (2) inside it for resetting the global_trace to the
original size.
(2) was also implemented in other place. So this patch assembles
