net: phy: fix phy_start to consider PHY_IGNORE_INTERRUPT

Browse Source 
[ Upstream commit 08f5138512 ]

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.
