perf evlist: Fix creation of cpu map
Currently, 'perf record -- sleep 1' creates a cpu map for all online
cpus since it turns out calling cpu_map__new(NULL). Fix it.
Also it is guaranteed that cpu_list is NULL if PID/TID is given by
calling perf_target__validate(), so we can make the conditional bit
simpler.
This also fixes perf test 7 (Validate) failure on my 6 core machine:
$ cat /sys/devices/system/cpu/online
0-11
$ ./perf test -v 7
7: Validate PERF_RECORD_* events & perf_sample fields:
--- start ---
perf_evlist__mmap: Operation not permitted
---- end ----
Validate PERF_RECORD_* events & perf_sample fields: FAILED!
