ide-dma: fix ide_build_dmatable() for TRM290
Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes,
judging from the code immediately preceding this check. So, we must never try
to "split" the PRD for TRM290.
This is probably never hit anyway -- with the DMA buffers aligned to at least
512 bytes and ATAPI DMA not being used for non block I/O commands...
