ubifs bad superblock bug
This patch fixes an issue when ubifs reads a bad superblock. Later it
tries to free memory, that was not allocated, which freezes u-boot.
This is fixed by looking for a non null pointer before free.
The message I got before u-boot freezes:
UBI: max/mean erase counter: 53/32
UBIFS: mounted UBI device 0, volume 1, name "rootfs"
UBIFS: mounted read-only
