[0/4] hw/dma: Add error handling for loading descriptions failing

Message

Fea.Wang June 3, 2024, 5:52 a.m. UTC

The original code assumes that memory transmission is always successful,
but in some cases, it gets bus-error.

Add error handling for DMA reading description failures. Do some
reasonable settings, and return the corrected transmission size.
Finally, return the error status.
