hw/nvme: Abort copy command when format is one while pif 

As per the NVMe Command Set specification Section 3.2.2, if

  i)  The namespace is formatted to use 16b Guard Protection
      Information (i.e., pif = 0) and
  ii) The Descriptor Format is not cleared to 0h

Then the copy command should be aborted with the status code of Invalid
Namespace or Format
