Leon HwangandGreg Kroah-Hartman 3c9e7909df bpf, verifier: Correct tail_call_reachable for bpf prog ...

[ Upstream commit 01793ed86b ]

It's confusing to inspect 'prog->aux->tail_call_reachable' with drgn[0],
when bpf prog has tail call but 'tail_call_reachable' is false.

This patch corrects 'tail_call_reachable' when bpf prog has tail call.
