net/mlx5: remove device status check in flow creation

[ upstream commit 4095ce34095e33ae9e8b19150b9280ff8737a590 ]

The flow rule can be inserted even before the device started. The
only exception is for a queue or RSS action.

For the other interfaces of template API, the start status is not
checked. The checking would cause some cache miss or eviction since
the flag locates on some other cache line.

Fixes: f1fecff ("net/mlx5: support Direct Rules action template API")
