REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1259
According to the the NVM Express spec Revision 1.1, for some commands,
command-related information will be stored in the Dword 0 of the
completion queue entry.
One case is for the Get Features Command (Section 5.9.2 of the spec),
Dword 0 of the completion queue entry may contain feature information.
Hence, this commit will always copy the content of completion queue entry
to the PassThru packet regardless of the execution result of the command.
