Andrii Nakryiko dab46b04a1 bpf: Fix map leak in HASH_OF_MAPS map ... [ Upstream commit 1d4e1eab456e1ee92a94987499b211db05f900ea ] Fix HASH_OF_MAPS bug of not putting inner map pointer on bpf_map_elem_update() operation. This is due to per-cpu extra_elems optimization, which bypassed free_htab_elem() logic doing proper clean ups. Make sure that inner map is put properly in optimized case as well.
