nbd: Include error names in trace messages
NBD errors were originally sent over the wire based on Linux errno values; but not all the world is Linux, and not all platforms share the same values. Since a number isn't very easy to decipher on all platforms, update the trace messages to include the name of NBD errors being sent/received over the wire. Tweak the trace messages to be at the point where we are using the NBD error, not the translation to the host errno values.
