When the caller reports that second error similarly, this produces two consecutive error messages on stderr or the HMP monitor. When the caller does something else with it, such as send it via QMP, the first error still goes to stderr or the HMP monitor. Fortunately, no such caller exists. Simply use the first error as is. Update expected output of qemu-iotest 049 accordingly.
