[PATCH v4 09/25] net/ixgbe: simplify vector PMD compilation

[Anatoly Burakov <anatoly.burakov@intel.com>]

Currently, there's a bunch of vector PMD-related stuff that's being
compiled based on what architecture the code is being compiled for.

Simplify it by removing necessary #ifdef's and have it so that vector PMD
compilation is controlled in one place - using a compile flag from the
build file.
