ubi-utils: ubiformat.c: convert to integer arithmetic
Do not cast percent to double, it is just used as upper limit.
Avoid floating point to fix compilation for aarch64 against klibc:
error: '-mgeneral-regs-only' is incompatible with floating-point code
| int percent = ((double)si->ok_cnt)/si->good_cnt * 100;
| ^~~~~~~
Notes:
* The checks in the code above this line ensure that si->good_cnt is not 0.
* The code assumes si->good_cnt * 100 will not overflow, then we can use
(si->ok_cnt * 100) safely because the former is bigger.
* The truncated result does not affect the logic:
i.e. a value of 49.9 is truncated to 49 and is still <50.
