Commit 660c486590aa ("PCI: dwc: Set 32-bit DMA mask for MSI target
address allocation") added dma_mask_set() call to explicitly set
32-bit DMA mask for MSI message mapping, but for now it throws a
warning on ret == 0, while dma_set_mask() returns 0 in case of
success.
Fix this by inverting the condition.
Misc: remove redundant braces around single statement.
