[PATCH 1/1] net/mlx5: fix memoy leak after device spawn failure

[Yunjian Wang <wangyunjian@huawei.com>]

In mlx5_dev_spawn() allocated memory for the 'priv->flows',
we should free it when errors occur, otherwise it will lead
to memory leak.

Fixes: b4edeaf3efd5 ("net/mlx5: replace flow list with indexed pool")
