[U-Boot] [PATCH] env_sf - Do not free flash environment on successful read

[Oliver Dillinger <oliver.dillinger@ttcontrol.com>]

In env_relocate_spec(), env_flash is freed and set to NULL
if CONFIG_ENV_OFFSET_REDUND is undefined. This leads to an
"Environment SPI flash not initialized" error when
performing a saveenv.

Oliver
