net: phy: marvell10g: fix null pointer dereference
Commit c3e302edca24 ("net: phy: marvell10g: fix temperature sensor on 2110")
added a check for PHY ID via phydev->drv->phy_id in a function which is
called by devres at a time when phydev->drv is already set to null by
phy_remove function.
This null pointer dereference can be triggered via SFP subsystem with a
SFP module containing this Marvell PHY. When the SFP interface is put
down, the SFP subsystem removes the PHY.
Fixes: c3e302edca24 ("net: phy: marvell10g: fix temperature sensor on 2110")
