Subject: [PATCH 1/1 net-next]: s2io: Fix log messages using dev->name

s2io driver is printing dev->name before its assignment (by
dev_alloc_name()), so "eth%d" is printed instead of "eth0", "eth1", etc.
Here is an example gotten from dmesg: 

eth%d: Enabling MSIX failed
eth%d: MSI-X requested but failed to enable

This patch calls dev_alloc_name() earlier, before any message being
printed, hence dev->name is translated from "eth%d" to "eth0", for
example, and all those prints become correct.
