iavf: Fix displaying queue statistics shown by ethtool

Browse source

Driver provided too many lines as an output to ethtool -S command.
Return actual length of string set of ethtool stats. Instead of predefined
maximal value use the actual value on netdev, iterate over active queues.
Without this patch, ethtool -S report would produce additional
erroneous lines of queues that are not configured.
