Masami Hiramatsu (Google) 9a6be23eb0 tracing: probe-events: Add comments about entry data storing code ...

[ Upstream commit bb9c6020f4 ]

Add comments about entry data storing code to __store_entry_arg() and
traceprobe_get_entry_data_size(). These are a bit complicated because of
building the entry data storing code and scanning it.

This just add comments, no behavior change.
