net loopback: change the nloopbacks default back from 4 to 8

We have several machines with four integrated NICs that currently do not have functional drivers. We add a more common NIC to the machine to get things working. Since the integrated NICs get assigned interfaces eth0 - eth3 and the add-in NIC eth4, we do not get a loopback interface for eth4 because it is the fifth interface. It also seems likely in a data center that machines could use more that four network interfaces.

This patch changes the nloopbacks parameter default back from 4 to 8.
