iavf: Fix TC config comparison with existing adapter TC config

[ Upstream commit 54976cf5 ]

Same number of TCs doesn't imply that underlying TC configs are
same. The config could be different due to difference in number
of queues in each TC. Add utility function to determine if TC
configs are same.
