REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1142 According to the the NVM Express spec Revision 1.1, for some commands (like Get/Set Feature Command, Figure 89 & 90 of the spec), the Memory Buffer maybe optional although the command opcode indicates there is a data transfer between host & controller (Get/Set Feature Command, Figure 38 of the spec). Hence, this commit refine the checks for the 'TransferLength' and 'TransferBuffer' field of the EFI_NVM_EXPRESS_PASS_THRU_COMMAND_PACKET structure to address this issue.
