Andrii Nakryiko fe58e3dd6e bpf: Fix map leak in HASH_OF_MAPS map 
[ Upstream commit 1d4e1eab45 ]

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.

Fixes: 8c290e60fa ("bpf: fix hashmap extra_elems logic")
