misc: pci_endpoint_test: Refactor dma_set_mask_and_coherent() logic
dma_set_mask_and_coherent() should never fail when the mask is >= 32bit,
unless the architecture has no DMA support. So no need to check for the
error and also no need to set dma_set_mask_and_coherent(32) as a fallback.
Even if dma_set_mask_and_coherent(48) fails due to the lack of DMA support
(theoretically), then dma_set_mask_and_coherent(32) will also fail for the
same reason. So the fallback doesn't make sense.
Simplify the code by setting the streaming and coherent DMA mask to 48
bits.
