net/mlx4_en: fix mlx4 ethtool -N insertion

Browse source 
[ Upstream commit 34e59836565e36fade1464e054a3551c1a0364be ]

ethtool expects ETHTOOL_GRXCLSRLALL to set ethtool_rxnfc->data with the
total number of entries in the rx classifier table.  Surprisingly, mlx4
is missing this part (in principle ethtool could still move forward and
try the insert).

Tested: compiled and run command:
	phh13:~# ethtool -N eth1 flow-type udp4  queue 4
	Added rule with ID 255
