gm20b_pbdma_handle_intr is only initializing pbdma_status when either pbdma_intr_0 or pbdma_intr_1 is pending. This could lead to using non-initialized chsw_status in gv11b_fifo_preempt_poll_pbdma, and causing unexpected failures in unit tests. Read pbdma_status before checking for pbdma interrupts, to make sure pbdma_status contains valid data.
