phy: core: Fixup return value of phy_exit when !pm_runtime_enabled
phy: core: Fixup return value of phy_exit when !pm_runtime_enabled

When phy_pm_runtime_get_sync() returns -ENOTSUPP, phy_exit() also returns
-ENOTSUPP if !phy->ops->exit. Fix it.
Also move the code to override ret close to the code we got ret.
I think it is less error prone this way.
