Yoshihiro Shimoda d66a530c10 PCI: endpoint: functions/pci-epf-test: Fix dma_chan direction 
[ Upstream commit 880d51c729 ]

In pci_epf_test_init_dma_chan() epf_test->dma_chan_rx is assigned from
dma_request_channel() with DMA_DEV_TO_MEM as filter.dma_mask.

However, in pci_epf_test_data_transfer() if the dir is DMA_DEV_TO_MEM,
epf->dma_chan_rx should be used but instead we are using
epf_test->dma_chan_tx.

Fix it.
