usb-storage: Fix share-rw option parsing

Because usb-storage creates an internal scsi device, we should propagate
options. We already do so for bootindex etc, but failed to take care of
share-rw. Fix it in an apparent way: add a new parameter to
scsi_bus_legacy_add_drive and pass in s->conf.share_rw.
