i2c-cpm: Detect and report NAK right away instead of timing out
Make the driver report an ENXIO error immediately upon NAK instead of
waiting for another interrupt and getting a timeout.
When reading from a device that is not present or declines to respond
to, e.g., a non-existent register address, CPM immediately reports a
NAK condition in the TxBD, but the driver kept waiting until a timeout,
which takes 1 second and causes an ugly console error message.
