[net-next 04/11] e1000e: cleanup - check return values consistently

From: Bruce Allan <bruce.w.allan@intel.com>

The majority of the e1000e code checks most function return values using a
test like 'if (ret_val)' or 'if (!ret_val)' but there are a few instances
of 'if (ret_val == 0)'. This patch converts the latter to the former for
consistency.
