igbvf: Fix code comments and whitespace
Fix the code comments to align with the drivers/net/ commenting style. Also fix other checkpatch errors such as using tabs where possible and properly wrap lines to conform to the 80 char limit (unless it is a string). Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com>
