cls_bpf: also dump TCA_BPF_FLAGS
In commit 43388da42a49 ("cls_bpf: introduce integrated actions") we have added TCA_BPF_FLAGS. We can also retrieve this information from the prog, dump it back to user space as well. It's useful in tc when displaying/dumping filter info. Also, remove tp from cls_bpf_prog_from_efd(), came in as a conflict from a rebase and it's unused here (later work may add it along with a real user).
