pulse-server: module: do not schedule unloading multiple times

Browse source 
While it is not a problem since `module_free()` calls
`pw_work_queue_cancel()`, it is completely unnecessary
to do it more than once.

Introduce a new flag on the module which stores whether or
not an unloading has been scheduled.
