Check file system validity before reading opening.bnr
This happened to work without any problems because the only way for a
file system to be invalid was to not have the right GC/Wii magic word
in the unencrypted area, and a volume could not be created without
having the right GC/Wii magic word there. Now that file systems read
the magic word from a partition instead, a fix is needed.
