Alexander Couzens 78cdeb665f net: usb: asix: replace mii_nway_restart in resume path
[ Upstream commit 5c968f48021a9b3faa61ac2543cfab32461c0e05 ]

mii_nway_restart is not pm aware which results in a rtnl deadlock.
Implement mii_nway_restart manual by setting BMCR_ANRESTART if
BMCR_ANENABLE is set.

To reproduce:
* plug an asix based usb network interface
* wait until the device enters PM (~5 sec)
* `ip link set eth1 up` will never return
