ipacess-config: Handle NVATTR NACKs in ipaccess-config

Currently we send the attribute changes in a send and forget
fashion. But sometimes the nanoBTS is sending us a NACK, e.g
with a invalid unit id. Start handling the NACK and provide
an error message to the user. The error message is not yet
describing the cause of the error but this is a slight progress
to the previous silent failure.
