If double buffering is not required in DmaMap(), the returned device address is passed through ConvertToPhysicalAddress () to convert the host address (which in case of DebugUncachedMemoryAllocationLib is not 1:1 mapped) to a physical address, which is what a device would expect to be able to perform DMA. By the same reasoning, a double buffer allocated using DmaAllocateBuffer () should be converted in the same way, considering that the buffer is allocated using UncachedAllocatePages (), to which the above equally applies. So add the missing ConvertToPhysicalAddress () invocation.
