Christophe Kerello bf6b61c8a7 mmc: mmci: stm32: fix DMA API overlapping mappings warning 
[ Upstream commit 6b1ba3f9040be5efc4396d86c9752cdc564730be ]

Turning on CONFIG_DMA_API_DEBUG_SG results in the following warning:

DMA-API: mmci-pl18x 48220000.mmc: cacheline tracking EEXIST,
overlapping mappings aren't supported

DMA API debug brings to light leaking dma-mappings as dma_map_sg and
dma_unmap_sg are not correctly balanced.

If an error occurs in mmci_cmd_irq function, only mmci_dma_error
function is called and as this API is not managed on stm32 variant,
dma_unmap_sg is never called in this error path.
