Subject: [PATCH] nes: fix reversed IP address

commit 63779436ab4ad0867bcea53bf853b0004d7b895di (drivers: replace NIPQUAD())
accidentally replaced two HIPQUAD()s causing IP addresses to be
printed in reverse order, add two temporary local vars.

Signed-off-by: Harvey Harrison <harvey.harrison@...il.com>

I'll start working on a patch working directly with _be32s, but this
is the safest for now.
