Hangbin Liu a0f2b7acb4 libbpf: Close map fd if init map slots failed
Previously we forgot to close the map fd if bpf_map_update_elem()
failed during map slot init, which will leak map fd.

Let's move map slot initialization to new function init_map_slots() to
simplify the code. And close the map fd if init slot failed.
