Subject: [PATCH] perf bpf-loader: Add missing '*' for key_scan_pos

key_scan_pos is a pointer for getting scan position in
bpf__obj_config_map() for each BPF map configuration term,
but it's misused when error not happened.

Fixes: 066dacbf2a32 ("perf bpf: Add API to set values to map entries in a bpf object")
