net: netsec: fix error handling in netsec_register_mdio()
[ Upstream commit 94423589689124e8cd145b38a1034be7f25835b2 ]
If phy_device_register() fails, phy_device_free() need be called to
put refcount, so memory of phy device and device name can be freed
in callback function.
If get_phy_device() fails, mdiobus_unregister() need be called,
or it will cause warning in mdiobus_free() and kobject is leaked.
