net: Fix usage of pskb_trim_rcsum
[ Upstream commit 6c57f0458022298e4da1729c67bd33ce41c14e7a ]
In certain cases, pskb_trim_rcsum() may change skb pointers.
Reinitialize header pointers afterwards to avoid potential
use-after-frees. Add a note in the documentation of
pskb_trim_rcsum(). Found by KASAN.
