Subject: [PATCH] extensions: cluster: Avoid undefined shift
Value 1 is signed by default and left-shifting by 31 is undefined for
those. Fix this by marking the value as unsigned.
Fixes: 64a0e09894e52 ("extensions: libxt_cluster: Add translation to nft")
(cherry picked from commit 28c16371cdad16707674450b59919e3d97185694)
