https://webrtc-review.googlesource.com/c/src/+/119121 added two calls to set the observed overhead. Both SetupSendCodec() and ReconfigureSendCodec() update the encoder's overhead. However, these calls happen before RTP has issued any callbacks to set the overhead, so they tell the encoder that the overhead is zero.
This change checks whether the overhead has been set to a non-zero value before each of the new calls and adds a DCHECK to quickly catch future cases which attempt to set overhead to zero.
