Fred Li 11ec79f5c7 bpf: Fix a segment issue when downgrading gso_size 
[ Upstream commit fa5ef655615a01533035c6139248c5b33aa27028 ]

Linearize the skb when downgrading gso_size because it may trigger a
BUG_ON() later when the skb is segmented as described in [1,2].

Fixes: 2be7e212d5419 ("bpf: add bpf_skb_adjust_room helper")
