perf dso: Fix memory leak in dso__new_map()
[ Upstream commit 581e295a0f6b5c2931d280259fbbfff56959faa9 ]
ASan reports a memory leak when running:
# perf test "65: maps__merge_in".
The causes of the leaks are two, this patch addresses only the first
one, which is related to dso__new_map().
The bug is that dso__new_map() creates a new dso but never decreases the
refcount it gets from creating it.
This patch adds the missing dso__put().
