Subject: mtd-utils: common.c: convert to integer arithmetic
We use floating point just to print out KiB, MiB, GiB.
Avoid that to be klibc friendly.
Fixes compilation for aarch64 against klibc:
error: '-mgeneral-regs-only' is incompatible with floating-point argument
| printf("%s%.1f GiB", p, (double)bytes / (1024 * 1024 * 1024));
etc.
