Philipp Maier c1e95c844c MSC_ConnectionHandler: make as_handover more race robust 
The IPACC and MDCX interaction happens nearly in parallel to the
normal RSL connection that handles the handover, in particular the
channel relase from the old BTS may arrive in between IPACC and MGCP
operations.

- When the channel release arrives, check if MGCP and IPACC
  operations are done (we have seen one MDCX on MGCP and an CRCX
  plus an MDCX on IPACC level)
