[PATCH] perf util: Join four conditions in two in perf_evlist__create_maps().

[Dongsheng Yang]

There are four condition branchs in perf_evlist__create_maps, but they
only do two kinds of thing. 1st and 4th call cpu_map__new(), and the others
call cpu_map__dummy_new(). This patch joins them in two branchs, decreasing
the number of branch and removing some duplicated code.
