perf test: Fix hist testcases when kptr_restrict is on

Currently if kptr_restrict is enabled, all hist tests failed with
segfaults.  This is because machine__create_kernel_maps() in
setup_fake_machine() failed in that situation, and it called
machine__delete() on the error path.  But outer callers again called
machines__exit() causing double free for the host machine.
