coverity: Address issue found by coverity

Add NULL checks on the return value of call_leg_other() in
update_rtp()

If the remote side has requested media change and we cannot
find the other leg, then release call. This should not
happen.

Also, Add an assert to show that we cannot be here
without call type of SIP or MNCC (not related to coverity)
