PCI: epf-test: Fix DMA transfer completion initialization

Browse source

commit 4aca56f8ea upstream.

Reinitialize the transfer_complete DMA transfer completion before calling
tx_submit(), to avoid seeing the DMA transfer complete before the
completion is initialized, thus potentially losing the completion
notification.
