Subject: [PATCH AUTOSEL 6.7 066/108] selftests/bpf: fix compiler warnings in RELEASE=1 mode

From: Andrii Nakryiko <andrii@...nel.org>

[ Upstream commit 62d9a969f4a95219c757831e9ad66cd4dd9edee5 ]

When compiling BPF selftests with RELEASE=1, we get two new
warnings, which are treated as errors. Fix them.
