compositor: Don't free an uninitialised pointer.

Browse Source 
When backend_init returns NULL, we goto out_signals, which wants to
free(modules), but in this particular code path, modules hasn't been
initialised leading to a "Double-free or corruption" error message.
Initialising modules to NULL makes the free a no-op in this scenario.
