net: hisilicon: remove unexpected free_netdev

[ Upstream commit c758940158bf29fe14e9d0f89d5848f227b48134 ]

The net device ndev is freed via free_netdev when failing to register
the device. The control flow then jumps to the error handling code
block. ndev is used and freed again. Resulting in a use-after-free bug.
