net: mv643xx_eth: disable napi when init rxq or txq failed in mv643xx_eth_open()

[ Upstream commit f111606b63ff2282428ffbac0447c871eb957b6c ]

When failed to init rxq or txq in mv643xx_eth_open() for opening device,
napi isn't disabled. When open mv643xx_eth device next time, it will
trigger a BUG_ON() in napi_enable(). Compile tested only.
