provide return code from paging_request() function

this enables the caller to detect if the paging request was rejected
by the paging layer, especially in case it is already paging this very
subscriber.

In the case of SMS / 04.11, we used to have a memory leak of struct gsm_sms's,
since we would only free them from the paging succeeded/expired callbacks.
