the variables zero and unres_qlen_max are only used when CONFIG_SYSCTL is
defined, otherwise it causes the following sparse warning when we turn on
CONFIG_SYSCTL.

sorry for disturbing again, the sparse warning is
net/core/neighbour.c:65:12: warning: ‘zero’ defined but not used [-Wunused-variable]
net/core/neighbour.c:66:12: warning: ‘unres_qlen_max’ defined but not used [-Wunused-variable]

it happens if we turn off CONFIG_SYSCTL.

A patch for this has already in my tree for nearly a whole day.
