tracing: Use flexible array for entry fetch code

Browse source

Store probe entry fetch instructions in the probe_entry_arg
allocation instead of allocating a separate instruction array.

This keeps the entry fetch code tied to the entry argument lifetime while
leaving regular probe_arg instruction arrays separately allocated and
freed.
