UBIFS: Improve error message when reading superblock failed
In addition to the error message also display the error code. I had the
problem that my malloc memory was not enough (ENOMEM), and if u-boot
had displayed the error code immediately that would have saved me some
debugging.

Use ubifs_err instead of printf.
Add "errno=%d" in output as suggested by Albert Aribaud.
