radio hal: kill service if registration problem

This code isn't compiled with 'assert' enabled, and so we see this
compiler error:
[ 42% 27876/65807] target  C++: libril-cuttlefish-fork <= device/google/cuttlefish/guest/hals/ril/libril/ril_service.cpp
device/google/cuttlefish/guest/hals/ril/libril/ril_service.cpp:9931:27: warning: unused variable 'status' [-Wunused-variable]
        android::status_t status = radioService[i]->registerAsService(serviceNames[i]);

Probably, all usages of 'assert' should be changed, but for now fixing
this instance to silence compiler warnings. Turning on 'assert' here
could also work, but I've never really seen it used in Android.

Bug: N/A
Test: boot
