Manivannan SadhasivamandGreg Kroah-Hartman c994716d33 PCI: endpoint: pci-epf-test: Fix check for DMA MEMCPY test ...

[ Upstream commit 235c2b197a ]

Currently, if DMA MEMCPY test is requested by the host, and if the endpoint
DMA controller supports DMA_PRIVATE, the test will fail. This is not
correct since there is no check for DMA_MEMCPY capability and the DMA
controller can support both DMA_PRIVATE and DMA_MEMCPY.

Fix the check and also reword the error message.
