i40e/i40evf: Refactor i40e_debug_aq and make some functions static
A sparse complaint in i40e_debug_aq in a funky buffer write goes away by straightening out the code out to something less convoluted. Also fix some other sparse warnings while we are at it, making some functions static and using NULL instead of 0.
