accel/qaic: Declare BO 'sliced' after all the operations are complete

Once the BO is declared 'sliced' by setting bo->sliced to true we can
perform DMA (QAIC_EXECUTE_BO) operation on that BO. Hence we should
declare a BO sliced after completing all the operations.

Adding BO to its respective DBC list in qaic_attach_slicing_bo() seems
out of place as qaic_attach_slicing_bo() should just update BO with
slicing configuration.
