net: phy: Set SUPPORTED_1000baseX_Half flag in ESTATUS_1000_XHALF case

Commit de1d786e (add support for Xilinx 1000BASE-X phy (GTX)) introduced the
checking for ESTATUS_1000_XHALF, but it incorrectly sets the
SUPPORTED_1000baseX_Full flag in this case.

Set the SUPPORTED_1000baseX_Half flag instead.
