tracing/probes: Fix not to count error code to total length
commit b41326b5 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.
