Subject: [PATCH 3/6] perf machine: Fix the search for the kernel DSO on the unified list

From: Arnaldo Carvalho de Melo <acme@...hat.com>

When unifying the user_dsos and kernel_dsos a bug was introduced by
inverting the check for dso->kernel, fix it.

Fixes: 3d39ac538629 ("perf machine: No need to have two DSOs lists")
