Subject: [PATCH] netfilter: ip6_tables: remove redundant assignment to e

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

The assignment to variable e is redundant since the same assignment
occurs just a few lines later, hence it can be removed.  Cleans up
clang warning: warning: Value stored to 'e' is never read
