[PATCH net-next v2 4/8] net: macb: use the current queue number for stats

[Paolo Valerio <pvalerio@redhat.com>]

gem_get_ethtool_stats calculates the size of the statistics
data to copy always considering maximum number of queues.

The patch makes sure the statistics are copied only for the
active queues as returned in the string set count op.
