Thomas Fleury 87abec1ed9 gpu: nvgpu: pbdma_status in preempt poll 
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.
