PCI: epf-mhi: Fix the DMA data direction of dma_unmap_single() 

[ Upstream commit 327ec5f70609cf00c6f961073c01857555c6a8eb ]

In the error path of pci_epf_mhi_edma_write() function, the DMA data
direction passed (DMA_FROM_DEVICE) doesn't match the actual direction used
for the data transfer. Fix it by passing the correct one (DMA_TO_DEVICE).
