net: phy: genphy_10g_driver: Avoid NULL pointer dereference 

This driver got missed during the recent change of .features from a
u32 to a pointer to a Linux bitmap. Change the initialisation from 0
to PHY_10GBIT_FEATURES so removing the danger of a NULL pointer
dereference.

Fixes: 719655a149 ("net: phy: Replace phy driver features u32 with link_mode bitmap")
