[U-Boot] [PATCH] env: sf: fix return value of env_sf_load

[Simon Goldschmidt]

With the recent changes to support multiple environments, I see a
message "Failed (1)" when loading environment from sf.

env_sf_load() returns the return value of env_import(). This must be
'inverted' to return the correct meaning.
