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).

Bjorn, Krzysztof, I'd like to apply this patch to MHI tree on top of eDMA
async patches due to dependency:
