[PATCH net] net: phy: phy_device: free the phy_device on the phy_device_create error path

[Maxime Chevallier]

When error'ing out from phy_device_create(), the previously kzalloc'd "dev"
pointer gets overwritten with an error pointer, without freeing it
beforehand, thus leaking the allocated phy_device. Add the missing kfree
back.
