dmaengine: idma64: Add check for dma_set_max_seg_size
[ Upstream commit 2b1c1cf08a0addb6df42f16b37133dc7a351de29 ]
As the possible failure of the dma_set_max_seg_size(), it should be
better to check the return value of the dma_set_max_seg_size().
Fixes: e3fdb1894cfa ("dmaengine: idma64: set maximum allowed segment size for DMA")
