[PATCH] netfilter: remove unused variable

[Michal Nazarewicz]

From: Michal Nazarewicz <mina86@xxxxxxxxxx>

The nfmsg variable is not used (except in sizeof operator which does
not care about its value) between the first and second time it is
assigned the value.  Furthermore, nlmsg_data has no side effects, so
the whole assignment insruction can be safely removed.
