This commit adds serveral checks for the 'Packet' parameter passed to the EFI_NVM_EXPRESS_PASS_THRU_PROTOCOL.PassThru() API: The check for the 'TransferLength' field in EFI_NVM_EXPRESS_PASS_THRU_COMMAND_PACKET to make sure the value will not exceed the maximum data transfer size allowed by a controller. The check for the 'TransferBuffer' and 'TransferLength' fields in EFI_NVM_EXPRESS_PASS_THRU_COMMAND_PACKET when the Opcode of an NVME command indicates a data transfer between controller and host. The check for the 'MetadataLength' field in EFI_NVM_EXPRESS_PASS_THRU_COMMAND_PACKET to make sure the value is not 0 when the corresponding 'MetadataBuffer' field has a non-NULL value.
