[PATCH net-next v3 14/31] net: usb: use ndo_siocdevprivate

From: Arnd Bergmann <arnd@arndb.de>

The pegasus and rtl8150 drivers use SIOCDEVPRIVATE ioctls
to access their MII registers, in place of the normal
commands. This is broken for all compat ioctls today.

Change to ndo_siocdevprivate to fix it.
