perf test: Fix vmlinux failure on s390x
On s390x perf test 1 failed. It turned out that commit 4a084ecfc821
("perf report: Fix module symbol adjustment for s390x") was incorrect.
The previous implementation in dso__load_sym() is also suitable for
s390x.
Therefore this patch undoes commit 4a084ecfc821.
