MdeModulePkg NvmExpressDxe: Add NamespaceId validity check in PassThru

Browse Source 
According to the UEFI spec, EFI_NVM_EXPRESS_PASS_THRU_PROTOCOL.PassThru()
should return EFI_INVALID_PARAMETER if the input 'NamespaceId' is invalid
for the NVM Express controller. This commit adds check in PassThru() to
follow this rule.
