[Bug libstdc++/24217] filebuf.open call sets the error bits incorrectly

sample code:
fn(const char* fname)
{
   ifstream fstr;

   if (!fname)
      return;

   fstr.clear();
      fstr.open(fname, ios::in | ios::nocreate);
   if (!(fstr.is_open())) {
            cout << "rdstate():" << fstr.rdstate();
            cout << "bad():" << fstr.bad();
            cout << "fail():" << fstr.fail();
            return;
   }
//Read the file contents
}

As you can see, the fstr is a stack variable that is used to access the file. 
The flags were cleared before the open call. When it failed rdstate was set to
4.
This function call successfully opened the file multiple times before the
failure.
