Subject: bpf: Add missing newline characters in verifier error messages
Patch-mainline: v5.9-rc1
Git-commit: 4fc00b79b85d4c34bef06ad49f109ad7cd9e5d83
References: bsc#1177028

Newline characters are added in two verifier error messages,
refactored in Commit afbf21dce668 ("bpf: Support readonly/readwrite
buffers in verifier"). This way, they do not mix with
messages afterwards.
