Subject: [net v2 4/6] i40e: convert ret to aq_ret
From: Jesse Brandeburg <jesse.brandeburg@...el.com>
When calling admin queue functions the driver should use aq_ret
variable to help make clear that the return value is not a regular
return variable.
This allows for clean up of the return types that were previously
converted to int.
