[PATCH 11/15] perf evlist: Factor out a function to propagate maps for a single evsel

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

Subsequent fixes will need a function that just propagates maps for a
single evsel so factor it out.

[ Moved them to before perf_evlist__add() to avoid having to move it in the next patch ]
