====================
ibmvnic: Update firmware error reporting

This patch set cleans out a lot of dead code from the ibmvnic driver
and adds some more. The error ID field of the descriptor is not filled
in by firmware, so do not print it and do not use it to query for
more detailed information. Remove the unused code written for this.
Finally, update the message to print a string explainng the error
cause instead of just the error code.
