perf metricgroup: Fix metric expression copy leaks

Browse source

metricgroup__copy_metric_events() allocates a new metric expression and
duplicates metric_name before linking the expression into the destination
metric event.

Free new_expr when strdup() fails, and free the duplicated metric_name on
the later error paths.
