[libc] Fix incorrect unsigned comparison (#135595)
There is a problem with such unsigned comparison pattern:
```
if(unsigned_a - unsigned_b > 0) { /* only NOT go here when unsigned_a==unsigned_b */ }
```
When `unsigned_a` < `unsigned_b`, the result will still be `>0` due to
underflow.
This patch fixes two of the occurrences I found.
Also remove two redundant `if` where its condition is guaranteed by
outer `if`.
