With recent Nand (2MiB erase block), UBI/UBIFS is allocating a lot of RAM each
time a mtd device is attached and each time a ubifs volume is mounted.
The following patch makes UBI allocate peb_buf2 on demand.
Note: I'm not sure using vmalloc while holding buf_mutex is okay or not.
I'm waiting for you comments.
