Subject: [PATCH v2] PCI: endpoint: Remove surplus return statement from pci_epf_test_clean_dma_chan()

From: Wang Jiang <jiangwang@...inos.cn>

Remove a surplus return statement from the void function that has been
added in the commit commit 8353813c88ef ("PCI: endpoint: Enable DMA
tests for endpoints with DMA capabilities").

Especially, as an empty return statements at the end of a void functions
serve little purpose.

Otherwise, a warning will be issued when building the kernel with W=1:

  296: FILE: ./drivers/pci/endpoint/functions/pci-epf-test.c:296:
  return;
