usb-storage: Add rerror/werror properties
The error handling policy was traditionally set with -drive, but with -blockdev it is no longer possible to set frontend options. scsi-disk (and other block devices) have long supported qdev properties to configure the error handling policy, so let's add these options to usb-storage as well and just forward them to the internal scsi-disk instance.
