Subject: [PATCH AUTOSEL 5.4 02/31] selftests/bpf: satisfy compiler by having explicit return in btf test

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

[ Upstream commit f4c7e887324f5776eef6e6e47a90e0ac8058a7a8 ]

Some compilers complain about get_pprint_mapv_size() not returning value
in some code paths. Fix with explicit return.
