[PATCH bpf-next] bpf, test_run: Remove unnecessary prog type checks

From: Daniel Xu
Date: Sun May 29 2022 - 16:16:09 EST


These checks were effectively noops b/c there's only one way these
functions get called: through prog_ops dispatching. And since there's no
other callers, we can be sure that `prog` is always the correct type.
