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.

When the super block cannot be found it could indeed be that an envfs
was never written,...

... but when the super block is fine then a failure to read the data is
really that - a failure, no?

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!
