pulse: improve pa_operation compatibility

Browse source 
Methods that return a pa_operation should not return NULL.

pa_context_success_cb_t should return 1 on success and 0 on failure
with the error set in the context.

When a global is not found, let the info operation return eol = -1
with the error set in the context.
