net/mlx5e: check return value of rhashtable_init
When rhashtable_init() fails, it returns -EINVAL. However, since error return value of rhashtable_init is not checked, it can cause use of uninitialized pointers. So, fix unhandled errors of rhashtable_init. Signed-off-by: MichelleJin <shjy180909@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
