[U-Boot] [PATCHv2 3/4] env_nand.c: clarify log messages when env reading fails

The single message is misleading, since there is no equivalent success
note when reading the other copy succeeds. Instead, warn if one of the
redundant copies could not be loaded and emphasise on the error when
reading both fails.
