Antoine TenartandGreg Kroah-Hartman e4535dbb72 net-sysfs: take the rtnl lock when accessing xps_rxqs_map and num_tc ...

[ Upstream commit 4ae2bb8164 ]

Accesses to dev->xps_rxqs_map (when using dev->num_tc) should be
protected by the rtnl lock, like we do for netif_set_xps_queue. I didn't
see an actual bug being triggered, but let's be safe here and take the
rtnl lock while accessing the map in sysfs.
