Fix getService should retry on DEAD_OBJECT

If getService sees DEAD_OBJECT or nullptr when calling
interfaceChain on the retrieved service, it should
retry. Otherwise (e.g. TRANSACTION_FAILED for selinux
denials), it should bail out.

Test: calling Debug.getMemoryInfo from apps does not hang
Test: kill system_server, audio_server restarts exactly once
      (tested 10/10 times)
Test: taking screenshots / using camera / using maps
Test: adb push
$OUT/data/nativetest/VtsHalNfcV1_0TargetTest/VtsHalNfcV1_0TargetTest
/data/local/tmp && adb shell
/data/local/tmp/VtsHalNfcV1_0TargetTest
