Subject: [PATCH 12/21] netfilter: nf_tables: remove unused variable

From: YueHaibing <yuehaibing@...wei.com>

Variable 'ext' is being assigned but are never used hence they are
unused and can be removed.

Cleans up clang warnings:
net/netfilter/nf_tables_api.c:4032:28: warning: variable ‘ext’ set but not used [-Wunused-but-set-variable]
