net: phy: dp83640: clear state after PTP registration failure

Browse source

dp83640_probe() publishes its per-PHY state through phydev before
registering the PTP clock. If registration fails, the private data is
freed while phydev->mii_ts and phydev->priv still point to it, and
default_timestamp remains set.

Clear the published PHY state and reset the PTP clock pointer before
freeing the private data.
