MdeModulePkg NvmExpressDxe: Refine BuildDevicePath API to follow spec
According to the UEFI spec,
EFI_NVM_EXPRESS_PASS_THRU_PROTOCOL.BuildDevicePath() should return
EFI_NOT_FOUND when the input NamespaceId is not valid. However, current
code returns EFI_DEVICE_ERROR instead. This commit modifies the check for
input NamespaceId to return the correct status.
