I'd like to tweak the commit message a bit:

  qmp-dispatch: Use CommandNotFound error for disabled commands

  If a command is disabled an error is reported.  But due to usage of
  error_setg() the class of the error is GenericError which does not
  help callers in distinguishing this case from a case where a qmp
  command fails regularly due to other reasons.

  We used to use class CommandDisabled until the great error
  simplification (commit de253f1491 for QMP and commit 93b91c59db for
  qemu-ga, both v1.2.0).

  Use CommandNotFound error class, which is close enough.

Objections?
