Daniel Borkmann 1ab2de2bfe bpf: fix liveness propagation to parent in spilled stack slots
Using parent->regs[] when propagating REG_LIVE_READ for spilled regs
doesn't work since parent->regs[] denote the set of normal registers
but not spilled ones. Propagate to the correct regs.

Fixes: dc503a8ad9 ("bpf/verifier: track liveness for pruning")
