net: hisilicon: hns_dsaf_mac: fix mdio device leak in hns_mac_register_phy()

Browse source

hns_dsaf_find_platform_device() returns the mdio platform device with its
reference count incremented. hns_mac_register_phy() never drops that
reference, so the mdio device can not be released.

Release the reference on both the deferred probe and the normal path.
