vhost-scsi: init backend features earlier
As vhost core can use backend_features during init, clear it earlier to avoid using uninitialized memory. This use would be harmless since vhost scsi ignores the result anyway, but initializing earlier will help prevent valgrind errors, and make scsi and net behave similarly.
