net/mlx5: Avoid recovery in probe flows

Currently, recovery is done without considering whether the device is
still in probe flow.
This may lead to recovery before device have finished probed
successfully. e.g.: while mlx5_init_one() is running. Recovery flow is
using functionality that is loaded only by mlx5_init_one(), and there
is no point in running recovery without mlx5_init_one() finished
successfully.

Fix it by waiting for probe flow to finish and checking whether the
device is probed before trying to perform recovery.
