LOG: [OpenMP][runtime] Fix comparison of integer expressions of different signedness (#128204)

This PR fixes warning which occurs if one compiles OpenMP runtime with
GCC:
```
warning: comparison of integer expressions of different signedness: 'kmp_intptr_t' {aka 'long int'} and 'long unsigned int' [-Wsign-compare]
```
