Recently there was a treewide conversion of ACCESS_ONCE() to
{READ,WRITE}_ONCE(), but a new use was introduced concurrently by
commit:
1695849735752d2a ("perf mmap: Move perf_mmap and methods to separate mmap.[ch] files")
Let's convert this over to READ_ONCE() so that we can remove the
ACCESS_ONCE() definitions in subsequent patches.

The previous prep patch was just to show exactly what changed in that
function, now its time to move that method and things only it uses to
the right place, mmap.[ch]

To better organize the sources, and we may end up even using it
directly, without evlists and evsels.
