ThreadSanitizer: data race gstreamer/gst/gstpad.c:5543 in gst_pad_send_event_unchecked

This case suggested by the ThreadSanitizer occurs when updating the flags of the GstPad object while holding the object lock in gstpad.c, and when reading the flags in gst_base_src_loop(), unlocked: 

if (G_UNLIKELY (src->priv->flushing || GST_PAD_IS_FLUSHING (pad)))
