Subject: [PATCH 1/1] environment: "wrong magic" give the impression of an
error
Introduce a more soft wording when the magic of
the superblock does not match.
Include a hint to the typical reason "(envfs never written?)"
This prevents a "what is wrong?" moment when looking at
the boot log.
Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

v2:
Dropped change in envfs_load_data(). envfs_load_data() is used
to traverse the inodes and if we reach this far we
have encountered a real error which should be reported.
Thanks to Sascha for spottign this mistake!
