Subject: [Patch bpf-next v2 3/5] selftests/bpf: update elem_size check in map ptr test

From: Cong Wang <cong.wang@...edance.com>

In map ptr test, a hard-coded 64 is used to check hash element size.
Increase it to 72 as we increase the size of struct htab_elem. It
seems struct htab_elem is not visible here.
