This doesn't make any sense.  How can the environment be nowhere *and* also in 
flash, at the same time?

[Liu Gang-B34182] The environment cannot be nowhere *and* also in flash at the 
same time! So we should not
re-defined CONFIG_ENV_IS_IN_FLASH if the CONFIG_ENV_IS_NOWHERE has been 
defined. But the code will still define
CONFIG_ENV_IS_IN_FLASH if the CONFIG_ENV_IS_NOWHERE has been defined. This will 
cause a compilation error
described in this patch.
