If char is signed and one of these bytes happen to have a value outside
the ascii range, the corresponding output will consist of "ffffff"
followed by the two hex chars that were actually intended. One way to
fix it would be to change the casts to (u8*) aka
(unsigned char*), but it is much simpler (and generates smaller code)
to use the %ph extension which was created for such short hexdumps.

The driver is missing calls to pci_dma_mapping_error() after
performing the DMA mapping, which caused DMA-API warning to
show up in dmesg's output. Though that happens only when
DMA_API_DEBUG option is enabled. This change fixes the issue
and makes pvscsi_map_buffers() function more robust.

Add a function scsi_vpd_lun_id() to return a unique device
identifcation based on the designation descriptors of
VPD page 0x83.
As devices might implement several descriptors the order
of preference is:
- NAA IEE Registered Extended
- EUI-64 based 16-byte
- EUI-64 based 12-byte
- NAA IEEE Registered
- NAA IEEE Extended
A SCSI name string descriptor is preferred to all of them
if the identification is longer than 16 bytes.
The returned unique device identification will be formatted
as a SCSI Name string to avoid clashes between different
designator types.
