Masami Hiramatsu (Google) ebc1972c2c tracing/probes: Fix to set arg size and fmt after setting type from BTF ...

commit 9a571c1e27 upstream.

Since the BTF type setting updates probe_arg::type, the type size
calculation and setting print-fmt should be done after that.
Without this fix, the argument size and print-fmt can be wrong.
