Describe the update
This update fixes a problem where the simulation will crash in the volcano extension init subroutine on non-root threads if the volcano extension is turned off, such as in the transport tracer simulation. The fix moves the return if extension number is zero to directly after the call to retrieve extension number. This is the same handling as all other HEMCO extension initialization routines.
Expected changes
The model will not crash if the volcano extension is turned off.
