perf top: Fix unresolved comm when -s comm is used
The perf top uses 'dso,symbol' sort keys by default so it overlooked a problem in task's comm resolving. When the sort key contains 'comm', some task's comm is not shown properly. This is because the perf_top__mmap_read_idx() checks the cpumode value improperly. The cpumode value of non-sample events are 0 (PERF_RECORD_MISC_CPUMODE_ UNKNOWN) so the events will be ignored by the switch statement. This patch allows it for non-sample events.
