Kees Cook be4d46edee dmaengine: dw-axi-dmac: Do not dereference NULL structure 
If "vdesc" is NULL, it cannot be used with vd_to_axi_desc(). Leave
"bytes" unchanged at 0. Seen under GCC 13 with -Warray-bounds:

../drivers/dma/dw-axi-dmac/dw-axi-dmac-platform.c: In function 'dma_chan_tx_status':
../drivers/dma/dw-axi-dmac/dw-axi-dmac-platform.c:329:46: warning: array subscript 0 is outside array bounds of 'struct
virt_dma_desc[46116860184273879]' [-Warray-bounds=]
  329 |                 bytes = vd_to_axi_desc(vdesc)->length;
      |                                              ^~
