rtpbasedepayload: Make stats creation threadsafe, fix a CRITICAL

Use the object lock to protect the internal segment when updating
against access from getting the stats property.

Fix a critical in gst-inspect or when retrieving the stats
before any segment has arrived by checking whether the
segment has been initted..
