nand: Correct NAND erase percentage output
For NAND erase sizes smaller than one NAND erase block, erase
percentage output becomes grater than 100% e.g.
-- cut --
> nand info
Device 0: NAND 64MiB 1,8V 8-bit, sector size 16 KiB
> nand erase 0x100000 0x2000
NAND erase: device 0 offset 0x100000, size 0x2000
Erasing at 0x100000 -- 200% complete.
OK
>
-- cut --
Correct this and give user a warning that more is erased than specified:
-- cut --
> nand erase 0x100000 0x2000
NAND erase: device 0 offset 0x100000, size 0x2000
Warning: Erase size 0x00002000 smaller than one erase block 0x00004000
Erasing 0x00004000 instead
Erasing at 0x100000 -- 100% complete.
OK
>
-- cut --
