drivers: net: xgene: disable napi when register irq failed in xgene_enet_open()

[ Upstream commit ce9e57feeed81d17d5e80ed86f516ff0d39c3867 ]

When failed to register irq in xgene_enet_open() for opening device,
napi isn't disabled. When open xgene device next time, it will reports
a invalid opcode issue. Fix it. Only be compiled, not be tested.
