perf util: Fix do_read() to fail on EOF instead of busy-looping
While toying with perf, I've noticed that perf record can
easily enter a busy loop when doing something as silly as:
$ perf record -A ls
Yeah, do_read here really wants to read a known size, not being
able to should die(), not busy-loop ;)
That was the cause for the bug.
