Michael Brown a8442750e6 [efi] Avoid requesting zero-length DMA mappings ...

The UEFI specification does not prohibit zero-length DMA mappings.
However, there is a reasonable chance that at least one implementation
will treat it as an invalid parameter.  As a precaution, avoid calling
EFI_PCI_IO_PROTOCOL.Map() with a length of zero.
