Masami Hiramatsu 1154c95760 perf tools: Fix machine__create_kernel_maps to put kernel dso refcount 
Fix machine__create_kernel_maps() to put kernel dso because the dso has
been gotten via __machine__create_kernel_maps().

Refcnt debugger shows:

Actually, dsos__findnew gets the dso before returning it, so the dso
user (in this case machine__create_kernel_maps) has to put the dso after
used.
