4.14-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 08f5138512180a479ce6b9d23b825c9f4cd3be77 ]
This condition wasn't adjusted when PHY_IGNORE_INTERRUPT (-2) was added long ago. In case of PHY_IGNORE_INTERRUPT the MAC interrupt indicates also PHY state changes and we should do what the symbol says.
