1. Set d_call to null to prevent potential use after free …

   plugman_audio_callback in p25_recorder_decode is sometimes
   call when d_call is an invalid pointer. This seems to be some form
   of race condition where d_call has been freed immediately
   before the audio callback is called, causing a segmentation fault
   in the simplestream plugin on line 63 (`call->get_system()`).
   By setting d_call to null when `p25_recorder_decode::stop()`
   is called,  we can check for it being invalid before a plugin
   ever sees it, preventing a use-after-free segmentation fault.
