Fix null-pointer dereference in RTPSenderVideo.

Fix null-pointer dereference in RTPSenderVideo.

Since the address of the dereference is taken this inputs a garbage
almost-null pointer into RtpPacketizer. Not likely that a load/store is
performed on the address, but UBSan fires and it's a source of potential
future errors.
