net: intel: Cleanup the copyright/license headers

After many years of having a ~30 line copyright and license header to our
source files, we are finally able to reduce that to one line with the
advent of the SPDX identifier.

Also caught a few files missing the SPDX license identifier, so fixed
them up.

ixgbevf: Fix code comments and whitespace

Fix the code comments to align with drivers/net/ code commenting style,
