perf evlist: Amend mmap ref counting for the AUX area mmap
Reference counting of the mmap buffer does not work correctly when there is an AUX area mmap also. In snapshot mode it is not easy to know if the AUX area mmap buffer contains usefull information. Equally the evlist does not know if the recording is in sanpshot mode anyway. Consequently, for now just assume the AUX area mmap always has data, which will just cause the mmap buffer to remain mmapped for the duration of the recording.
