[issue26387] Race condition in sqlite module

[Filipp Andjelo]

New submission from Filipp Andjelo:

Race condition in sqlite close/dealloc crashes the application with double 
free(). The pointer is set to NULL outside of mutexed zone, so if close and 
dealloc follow each other very shortly application crashes. Please see the 
attached patch.
