[OpenMP][Offloading] Fix the issue that omp_get_num_devices returns
wrong number of devices, by Shiley Tian.
Summary: This patch is to fix issue in the following simple case:
  #include <omp.h>
 #include <stdio.h>
  int main(int argc, char *argv[]) {
   int num = omp_get_num_devices();
   printf("%d\n", num);
    return 0;
 }
Currently it returns 0 even devices exist. Since this file doesn't
contain any target region, the host entry is empty so further actions
like initialization will not be proceeded, leading to wrong device
number returned by runtime function call.
