Subject: [net-next 07/15] i40e: Report cmd->data in ETHTOOL_GRXCLSRLCNT instead of ETHTOOL_GRXCLSRULE

From: Anjali Singhai Jain <anjali.singhai@...el.com>

Based on review feedback from upstream cmd->data is not
defined in ETHTOOL_GRXCLSRULE but needs to be reported in
ETHTOOL_GRXCLSRLCNT. Also use a helper function to calculate the total
filter count.
