Before performing gpu device reset, first all level zero resources and gpu device specific resources have to be cleaned up. Also as after device reset, state of gpu device would be lost. Hence after performing gpu device reset, level zero device have to be reinitialized by querying gpu device again. This change is aimed at reinitializing the level zero resources after gpu device reset, so that user could continue using level zero devices after device reset.
