net/mlx5: Move health and page alloc init to mdev_init
Software structure initialization should be in mdev_init stage. This provides a better logical separation of mlx5 core device initialization flow and will help to seamlessly support creating different mlx5 device types such as PF, VF and SF mlx5 sub-function virtual device. This patch does not change any functionality. Signed-off-by: Vu Pham <vuhuong@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
