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

Browse Source 
[ Upstream commit f111606b63 ]

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.

Fixes: 2257e05c17 ("mv643xx_eth: get rid of receive-side locking")
