e100, e1000, ixgb: Fix an impossible memory overwrite bug
We keep getting requests from people that think that this might be an exploitable hole where we would overwrite 4 bytes in the netdev struct if the pci name would exceed 15 characters. In reality this will never happen but we fix it anyway. Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com>
