Frederic Konrad 1ee80592bf hw/dma/xlnx_csu_dma: don't throw guest errors when stopping the SRC DMA
UG1087 states for the source channel that: if SIZE is programmed to 0, and the
DMA is started, the interrupts DONE and MEM_DONE will be asserted.

This implies that it is allowed for the guest to stop the source DMA by writing
a size of 0 to the SIZE register, so remove the LOG_GUEST_ERROR in that case.

While at it remove the comment marking the SIZE register as write-only.
