Peter Ujfalusi b35f79aa46 mtd: rawnand: stm32_fmc2: Use dma_request_chan() instead dma_request_slave_channel() ...

dma_request_slave_channel() is a wrapper on top of dma_request_chan()
eating up the error code.

Use using dma_request_chan() directly and inform user of error in case the
DMA request failed.
