Complete fix is to wipe all usage of DHCP_NUM_TRIES_MAX.

Hi Olaf, thanks for sharing your patch.
With that anyway you miss the option of having different connections
that could fallback if the "primary" one with dhcp fails.
I would not trow away that feature.
A change in the default NetworkManager.conf can switch it off for
default connections leaving the feature there if needed:
