silent_call: remove unfinished fuzzer interface
Remove the fuzzer interface that was partially implemented in
gsm_04_08.c and silent_call.c is causing problems when an
SMS is sent during an active silent call. The reason for this
is that gsm0408_dispatch() in gsm_04_08.c would decide to
rout all uplink traffic to silent_call_rx() in silent_call.c.
silent_call_rx() is a stub function that discards the data.
This patch removes the fuzzer interface code by placing ifdefs
around it, so that it can be re-activated by experimentators.
