[PATCH 2/6] perf maps: Set the kmaps for newly created/added kernel maps

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

When using __maps__insert_sorted() the map kmaps field needs to be
initialized, as we need kernel maps to work with map__kmap().

Fix it by using the newly introduced map__set_kmap() method.
