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
Fixes: d9fe64e51114 ("net: asix: Add in_pm parameter")
