[PATCH v1 6/7] net/ntnic: add warning about service cores

[Serhii Iliushyk <sil-plv@napatech.com>]

This commit adds a warning message if the service cores are not available.
This warning notifies a user about potential issues with ntnic services.
There in no error because the service cores may be added
by application itself after the pcie_probe.
