Andrii Nakryiko 6d4eb36d65 bpf: Fix bpf_prog_test_run_xdp logic after incorrect merge resolution ... During recent net into net-next merge ([0]) a piece of old logic ([1]) got reintroduced accidentally while resolving merge conflict between bpf's [2] and bpf-next's [3]. This check was removed in bpf-next tree to allow extra ctx_in parameter passed for XDP test runs. Reinstating the check breaks bpf_prog_test_run_xdp logic and causes a corresponding xdp_context_test_run selftest failure. Fix by removing the check and allow ctx_in for XDP test runs.
