- Fix segfault pressing -> in 'perf top' with no hist entries. (Wang Nan)

   E.g:
	perf top -e page-faults --pid 11400 # 11400 generates no page-fault

- Fix propagation of thread and cpu maps, that got broken when doing incomplete
  changes to better support events with a PMU cpu mask, leading to Intel PT to
  fail with an error like:

    $ perf record -e intel_pt//u uname
    Error: The sys_perf_event_open() syscall returned with
              22 (Invalid argument) for event (sched:sched_switch).

  Because intel_pt adds that sched:sched_switch evsel to the evlist after the
  thread/cpu maps were propagated to the evsels, fix it. (Adrian Hunter)

The validation checks that the values that were just assigned, got
assigned i.e. the error can't ever happen.  Subsequent patches will call
this code in places where errors are not being returned.  Changing those
code paths to return this non-existent error is counter-productive, so
just remove it.

That in turn results in perf_evlist__set_maps not needing to return an
error, but callers aren't checking it either, so remove that too.
