dmaengine: xilinx: xdma: Workaround truncation compilation error
Increase length to be copied to be large enough to overcome the
following compilation error. The buf is large enough for this purpose.
drivers/dma/xilinx/xilinx_dpdma.c: In function ‘xilinx_dpdma_debugfs_desc_done_irq_read’:
drivers/dma/xilinx/xilinx_dpdma.c:313:39: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=]
313 | snprintf(buf, out_str_len, "%d",
| ^
drivers/dma/xilinx/xilinx_dpdma.c:313:9: note: ‘snprintf’ output between 2 and 6 bytes into a destination of size 5
313 | snprintf(buf, out_str_len, "%d",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
314 | dpdma_debugfs.xilinx_dpdma_irq_done_count);
