i40e: Fix the number of queues available to be mapped for use

BugLink: https://bugs.launchpad.net/bugs/1820948
Fix the number of queues per enabled TC and report available queues
to the kernel without having to limit them to the max rss limit so
they are available to be mapped for XPS. This allows a queue per
processing thread available for handling traffic for the given
traffic class.
