qemu: use QEMU_CAPS_STORAGE_WERROR for disk-error attributes

Browse Source 
When moving the formatting of this attributes from -drive
to -device, the QEMU_CAPS_USB_STORAGE_WERROR capability
was used, because usb-storage was the last device to gain
this capability.

However this lead to the assumption that QEMU binaries
without the usb-storage device do not support this,
leading to breakage on s390x with blockdev.
