MdeModulePkg NvmExpressDxe: Add check on the attributes of NVME controller
According to UEFI spec, an EFI_NVM_EXPRESS_PASS_THRU_PROTOCOL with neither
EFI_NVM_EXPRESS_PASS_THRU_ATTRIBUTES_LOGICAL nor
EFI_NVM_EXPRESS_PASS_THRU_ATTRIBUTES_PHYSICAL set in the Attributes field
is an illegal configuration.
This commit adds this check in the PassThru API to follow the spec.
