scsi-disk: Allow overriding SCSI INQUIRY removable bit
Provide the "removable" qdev property bit to override the SCSI INQUIRY
removable (RMB) bit for non-CDROM devices. This will be used by USB
Mass Storage Devices, which sometimes have this guest-visible bit set
and sometimes do not. They therefore requires a means for user
configuration.
