ROCm SMI CLI: Fix --showproductname bug

This patch fixes a --showproductname bug, which is related to the
device's SKU. If a device with a VBIOS value that cannot be decoded
is used, that device's SKU cannot be parsed out of the VBIOS string.

Now, when the VBIOS value cannot be decoded, an error will be
printed instead of crashing with an 'UnboundLocalError' message.
