[PATCH v2 1/7] bpf/validate: fix finished status on restart

[Marat Khalili]

If debug session is reused, requesting evaluation result while
evaluation is still in progress would successfully return result from
the previous evaluation instead of expected -EAGAIN error.

Make evaluation start clear the finished status.
