mtd: nand: Fix memory allocation in nanddev_bbt_init()
Fix the size of the buffer allocated to store the in-memory BBT.
This bug was previously hidden by a different bug, that was fixed in
commit d098093ba06e ("mtd: nand: Fix nanddev_neraseblocks()").
Fixes: 9c3736a3de21 ("mtd: nand: Add core infrastructure to deal with NAND devices")
