[PATCH bpf-next] bpf: fix precision propagation verbose logging

[Andrii Nakryiko <andrii@kernel.org>]

Fix wrong order of frame index vs register/slot index in precision
propagation verbose (level 2) output. It's wrong and very confusing as is.

Fixes: 529409ea92d5 ("bpf: propagate precision across all frames, not just the last one")
