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.
