5b9bd883 - [flang] Fix crash with USE of hermetic module file (#138785)

[flang] Fix crash with USE of hermetic module file (#138785) When one hermetic module file uses another, a later compilation may crash in semantics when it itself is used, since the module file reader sets the "current hermetic module file scope" to null after reading one rather than saving and restoring that pointer.
