Subject: net/mlx5: Start health poll at earlier stage of driver load
Patch-mainline: v6.1-rc1
Git-commit: 9b98d395b85dd042fe83fb696b1ac02e6c93a520
References: jsc#PED-1549
Start health poll at earlier stage, so if fw fatal issue occurred before
or during initialization commands such as init_hca or set_hca_cap the
poll health can detect and indicate that the driver is already in error
state.
