[U-Boot] [PATCHv3] env: Correct case of no sub-init function

[Tom Rini]

With the change to the environment code to remove the common init stage
of pointing to the default environment and setting it as valid, combined
with the change to switch gd->env_valid from 0/1/2 to an enum we now
must set env_valid to one of the enum values rather than an int.  And in
this case, not only was setting it to an int wrong, it was now the wrong
value.  Finally, in the case of ENV_IS_NOWHERE we must still say that
our envionrment is invalid after init for things to continue to
function.
