perf stat: Exit perf stat if parse groups fails

Browse Source 
Metrics were added by a callback but commit a4b8cfcabb ("perf
stat: Delay metric parsing") postponed this to allow optimizations based
on the CPU configuration.

In doing so it stopped errors in metric parsing from causing 'perf stat'
termination.

This change adds the termination for bad metric names back in.

Fixes: a4b8cfcabb ("perf stat: Delay metric parsing")
