perf stat: Add event parsing error handling to add_default_attributes
Add missing error handling for parse_events calls in add_default_attributes
functions. The error handler displays error details, like for transactions (-T):
Before:
$ perf stat -T
Cannot set up transaction events
After:
$ perf stat -T
Cannot set up transaction events
event syntax error: '..cycles,cpu/cycles-t/,cpu/tx-start/,cpu/el-start/,cpu/cycles-ct/}'
