Subject: [PATCH 19/22] sink_event_probe: do not keep duration in a variable

If not ENABLE_RECORDER, then duration is assigned a value
but is never used - as the compiler optimizes it out.

Fixes the following clang warning:
  src/channel-display-gst.c:443:21: warning: Value stored to
  'duration' during its initialization is never read
