Arnaldo Carvalho de Melo 57fc032ad6 perf session: Avoid infinite loop when seeing invalid header.size 
Vince reported that when fuzzing the userland perf tool with a bogus
perf.data file he got into a infinite loop in 'perf report'.

Changing the return of fetch_mmaped_event() to ERR_PTR(-EINVAL) for that
case gets us out of that infinite loop.
