skbuff: skb_segment: orphan frags before copying
[ Upstream commit 1fd819ecb90cc9b822cd84d3056ddba315d3340f ]
skb_segment copies frags around, so we need
to copy them carefully to avoid accessing
user memory after reporting completion to userspace
through a callback.
skb_segment doesn't normally happen on datapath:
TSO needs to be disabled - so disabling zero copy
in this case does not look like a big deal.
