I think it would be a bit tricky to solve it for general case. Consider
```fortran
subroutine foo()
  !$omp target
    call bar()
  !$omp end target
end subroutine foo
subroutine bar()
  call baz()
end subroutine bar()
subroutine baz()
  omp_set_default_device(2)
end subroutine baz()
```

We might need to do some sort of call graph traversal to accurately put this semantic check. Is it ok @kiranchandramohan if we do not handle this case?
