fdo#53521 Crash when running BASIC's "shell()" with a non-existent program
The problem is that the process handle is freed regardless of whether osl_executeProcess was successful or not. Therefore, a segmentation fault would result, as a random memory address would be freed. This patch checks whether osl_executeProcess was successful. If it was, then it frees the handle; if it wasn't successful, the memory is not freed.
