net: phy: smsc: Cope with hot-removal in interrupt handler
If reading the Interrupt Source Flag register fails with -ENODEV, then
the PHY has been hot-removed and the correct response is to bail out
instead of throwing a WARN splat and attempting to suspend the PHY.
The PHY should be stopped in due course anyway as the kernel
asynchronously tears down the device.
