[PATCH] netfilter: nf_tables: remove redundant variables 'create' and 'ext'

[YueHaibing <yuehaibing@huawei.com>]

Variables 'create' and 'ext'  are being assigned but are never used hence
they are redundant and can be removed.

Cleans up clang warnings:
net/netfilter/nf_tables_api.c:3364:7: warning: variable ‘create’ set but not used [-Wunused-but-set-variable]
net/netfilter/nf_tables_api.c:4032:28: warning: variable ‘ext’ set but not used [-Wunused-but-set-variable]
