ixgbe: remove tie between NAPI work limits and interrupt moderation
As noted by Ben Hutchings and David Miller, work limits for NAPI should not be tied to interrupt moderation parameters. This should be handled by NAPI, possibly through sysfs. Neil Horman & Stephen Hemminger are working on a solution for NAPI currently. In the meantime, remove this tie between work limits and interrupt moderation.
