Subject: [PATCH net-next 13/15] ice: Remove rx_gro_dropped stat

From: Anirudh Venkataramanan <anirudh.venkataramanan@...el.com>

Tracking of the rx_gro_dropped statistic was removed in
commit f73fc40327c0 ("ice: drop dead code in ice_receive_skb()").
Remove the associated variables and its reporting to ethtool stats.
