Subject: bpf: add bpf_clone_redirect to bpf_helper_changes_pkt_data

From: Daniel Borkmann <[email protected]>

[ Upstream commit 41703a731066fde79c3e5ccf3391cf77a98aeda5 ]

The bpf_clone_redirect() still needs to be listed in bpf_helper_changes_pkt_data() since we call into bpf_try_make_head_writable() from there, thus we need to invalidate prior pkt regs as well.
