net/mlx5: Stop waiting for PCI up if teardown was triggered

If driver teardown is called while PCI is turned off, there is a race
between health recovery and teardown. If health recovery already started
it will wait 60 sec trying to see if PCI gets back and it can recover,
but actually there is no need to wait anymore once teardown was called.

Use the MLX5_BREAK_FW_WAIT flag which is set on driver teardown to break
waiting for PCI up.
