Merge branch 'net-phy-remove-phy_error-from-phy_disable_interrupts'

Heiner Kallweit says:

====================
net: phy: remove 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().

v2:
- splitted into two separate patches
