fwu: mtd: Fix dfu_alt_info generation for 2 images per bank
Code rewrites the last char of size with adding &. It is visible from
dfu_alt_info print before this patch:
Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000
8000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000'
And after it:
Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000
80000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000'
Size for bank0 and bank1 must be the same because it is the same image.
