Subject: [PATCH] qemu: add QEMU_CAPS_STORAGE_WERROR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Detect the werror property on SCSI and virtio disks.
But clear it if the QEMU supports usb-storage device without it
also supporting this option for usb-storage.
