virtchnl: finish conversion to virtchnl interface
This patch implements the complete version of the virtchnl.h file with final renames, and fixes the related code in i40e and i40evf. It also expands comments, and adds details on the usage of certain fields. In addition, due to the changes a couple of casts are needed to prevent errors found by sparse after renaming some fields.
