tools/libbpf: Avoid possibly using uninitialized variable
Fixes a GCC maybe-uninitialized warning introduced by 48cca7e44f9f. "text" is only initialized inside the if statement so only print debug info there. Fixes: 48cca7e44f9f ("libbpf: add support for bpf_call") Signed-off-by: Jeremy Cline <jeremy@jcline.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
