xilinx: Return ENVL_NOWHERE instead of ENVL_UNKNOWN

The system refuses to boot without any environment, so return ENVL_NOWHERE when
there's nowhere to store the environment instead of ENVL_UNKNOWN.

This fixes that the board won't boot from eMMC when CONFIG_ENV_IS_IN_FAT is not
defined, for example. Similar for other combinations.
