Recent commit 75d28899e3e9 ("net: phy: Synchronize PHY interface modes with Linux") reordered the enum definitions. This caused the range of enums that this api was checking to go bad.
While it is possible for the phy drivers to practically use the enum's directly, drivers such as dp83867 use this helper to manage the configuration of the phy correctly.

Please also consider dropping this function, since it is used only in one driver drivers/net/phy/dp83867.c and that device does not actually support QUSGMII, USXGMII nor QSGMII. It only supports SGMII.
With rgmii, the corresponding phy_interface_is_rgmii() function makes sense, but for SGMII the four modes are entirely too different for this to make sense.
