Masami Hiramatsu (Google) 6ea2a408d3 tracing/probes: Fix not to count error code to total length ...

commit b41326b5e0 upstream.

Fix not to count the error code (which is minus value) to the total
used length of array, because it can mess up the return code of
process_fetch_insn_bottom(). Also clear the 'ret' value because it
will be used for calculating next data_loc entry.
