[PATCH v2 2/9] env: ext4: set gd->env_valid

[Patrick Delaunay]

Add a missing initialization of gd->env_valid in env_ext4_load
as it is already done in some other env device.

Set gd->env_valid = ENV_VALID in env_ext4_save() and env_ext4_load().

This patch allows to have a correct information in 'env info' command.
