Ludvig Pärsson f90b1cebc4 ethtool: netlink: Add missing ethnl_ops_begin/complete
[ Upstream commit f1172f3ee3a98754d95b968968920a7d03fdebcc ]

Accessing an ethernet device that is powered off or clock gated might
cause the CPU to hang. Add ethnl_ops_begin/complete in
ethnl_set_features() to protect against this.
