gprs_pcu: Explicitly free all bts objects in list before freeing pcu
This is mostly important to unit tests, where the gprs_pcu object is recreated several times (it is not recreated in normal operation). The BTS objects are already being freed through talloc dependency tree. However, since they may trigger counter updates, access to the pcu list, etc, let's better do it explicitly before erasing gprs_pcu object fields.
