Subject: [PATCH 5.10 37/86] netfilter: nftables: remove redundant assignment of variable err

From: Colin Ian King <colin.king@...onical.com>

[ Upstream commit 626899a02e6afcd4b2ce5c0551092e3554cec4aa ]

The variable err is being assigned a value that is never read,
the same error number is being returned at the error return
path via label err1.  Clean up the code by removing the assignment.

Addresses-Coverity: ("Unused value")
