After initiating a sideband transaction, we only want to wait for the transaction to become idle. If, as we are, we wait for both the busy and error flag to clear, if an error is raised we just spin until the timeout. Once the hw is idle, we can then check to see if the hw flagged an error, and report it distinctly. Signed-off-by:
