Mina Almasry 6f793a1d05 net: netmem: fix skb_ensure_writable with unreadable skbs ... skb_ensure_writable should succeed when it's trying to write to the header of the unreadable skbs, so it doesn't need an unconditional skb_frags_readable check. The preceding pskb_may_pull() call will succeed if write_len is within the head and fail if we're trying to write to the unreadable payload, so we don't need an additional check. Removing this check restores DSCP functionality with unreadable skbs as it's called from dscp_tg.
