mtd: nand: omap2: Don't call dma_release_channel() if dma_request_chan() failed
dma_request_chan() can fail returning an error pointer. In this case
prevent calling dma_release_channel() to prevent a ERR_PTR() dereference.
As error path can be called even with no DMA configuration, info->dma can
be NULL so don't call dma_release_channel() for that case either.
