qdev-monitor: Convert qbus_find() to Error
As usual, the conversion breaks printing explanatory messages after the error: actual printing of the error gets delayed, so the explanations precede rather than follow it. Pity. Disable them for now. See also commit 7216ae3. While there, eliminate QERR_BUS_NOT_FOUND, and clean up unusual spelling in the error message.
