so the pointer stored in this list is free after the umount.
On a new ubifs mount, the new allocated super_block struct
get inserted into the super_blocks list ... which contains
now a freed pointer, and the list_add_tail() corrupts the
freed memory ...
2 solutions are possible:
- remove the super_block from the super_blocks list
on umount
- as U-Boot does not use the super_blocks list ...
remove it complete for U-Boot.
Both solutions should not introduce problems for porting
