net: core: check skb_frags_readable before uncloning in skb_copy_ubufs
skb_copy_ubufs drops clones and modifies the SKB via pskb_expand_head()
before checking for !skb_frags_readable(skb). This alters the SKB
geometry prior to throwing an -EFAULT on an invalid SKB. Check
readability first.
Fixes: 65249feb6b3d ("net: add support for skbs with unreadable frags")
