Fix potential crash when building rtx packet

rtx packet may have addition extension (mid) and may use different
header size for extension (e.g. if repaired rtp stream id registered
to larger id than rtp stream id)

As a result rtx packet size calculation as orginial size + 2 bytes in
some scenarious may be incorrect. This chenage avoids crash in that cases.
