For multiple env drivers to correctly implement fallback when

There is more common code in mmc, nand and ubi env drivers that

For this, a status/error value whether the buffers were loaded

env_import (and env_import_redund) currently return 1 on success

Let's clean this up by making env_import and env_import_redund

env_get_f calls env_get_char to load single characters from the
environment. However, the return value of env_get_char was not
checked for errors. Now if the env driver does not support the
.get_char call, env_get_f did not notice this and looped over the
whole size of the environment, calling env_get_char over 8000

end.
Fix this by checking if env_get_char returns < 0.
