[PATCH] nfp: fix error return code in nfp_net_netdev_open()

[Wei Yongjun]

From: Wei Yongjun <weiyongj...@huawei.com>

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 73725d9dfd99 ("nfp: allocate ring SW structs dynamically")
Signed-off-by: Wei Yongjun <weiyongj...@huawei.com>
