| Fix potentially uninitialized value. |
| |
| Depending on what ReadOK does it's possible for |dircount16| to be used without |
| being initialized. The read code calls back into PDFium specific code which then |
| calls into the stream reading code. |
| |
| Initialize the value to be sure it is set. |
