Subject: [PATCH net-next] net: phy: remove call to phy_error from
 phy_disable_interrupts

All callers of phy_disable_interrupts() call phy_error() in the error
case. Therefore we don't need to do this within the function too.
This change also allows us to use phy_disable_interrupts() in code
holding phydev->lock (because phy_error() takes this lock).
Make use of this in phy_stop().
