Daniel Borkmann a8cf76a902 bpf: fix sg shift repair start offset in bpf_msg_pull_data
When we perform the sg shift repair for the scatterlist ring, we
currently start out at i = first_sg + 1. However, this is not
correct since the first_sg could point to the sge sitting at slot
MAX_SKB_FRAGS - 1, and a subsequent i = MAX_SKB_FRAGS will access
the scatterlist ring (sg) out of bounds. Add the sk_msg_iter_var()
helper for iterating through the ring, and apply the same rule
for advancing to the next ring element as we do elsewhere. Later
work will use this helper also in other places.

Fixes: 015632bb30 ("bpf: sk_msg program helper bpf_sk_msg_pull_data")
