mtd: fix arguments to bad block ioctls
In the Kernel the mtd ioctls expect a pointer to the offset, whereas
barebox interprets the pointer itself as an offset. Since we want
to add 64bit support for file sizes a pointer may not be sufficient,
so align with the kernel and convert it to a pointer to the offset.
