[Qemu-devel] [PATCH] block: Fix block-set-write-threshold not to use funky error class

[Markus Armbruster]

Error classes are a leftover from the days of "rich" error objects.
New code should always use ERROR_CLASS_GENERIC_ERROR.  Commit e246211
added a use of ERROR_CLASS_DEVICE_NOT_FOUND.  Replace it.
