Tomas Bortoli da32e0303d tracing: Avoid memory leak in predicate_parse() ...

commit dfb4a6f2191a80c8b790117d0ff592fd712d3296 upstream.

In case of errors, predicate_parse() goes to the out_free label
to free memory and to return an error code.

However, predicate_parse() does not free the predicates of the
temporary prog_stack array, thence leaking them.
