net/mlx5: Start health poll after enable hca

Browse Source 
The health poll mechanism performs periodic checks to detect firmware
errors. One of the checks verifies the function is still enabled on
firmware side, but the function is enabled only after enable_hca command
completed. Start health poll after enable_hca command to avoid a race
between function enabled and first health polling.
