[PATCH] net: Fix ehea warning when built in

[Michael Neuling <mikey@neuling.org>]

  Author: Olaf Hering <ohering@suse.com>
  drivers/net/ethernet/ibm/ehea/ehea_main.c: add alias entry for portN properties
We added ehea_module_device_table.  Unfortunately we only use this when
building as a module so we get the following warning when built in, like
in pseries_defconfig:

  drivers/net/ethernet/ibm/ehea/ehea_main.c:105:1: warning: 'ehea_module_device_table' defined but not used [-Wunused-variable]

This wraps ehea_module_device_table with #if MODULE.
