Subject: [PATCH] net: ethernet: gianfar_ethtool: remove redundant variable last_rule_idx

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

Variable last_rule_idx is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'last_rule_idx' set but not used [-Wunused-but-set-variable]
