osmo_gsup_encode(): Make coverity happy by invariant checking
gsm48_encode_bcd_number() can theoretically return a length in excess of
the size of the bcd_buf, but only in case an overly-long IMSI is passed
into the function (which would be illegal in the first place).
Change-Id: If3dc68ee13ff784b487bbc686b777cec9057d537
Fixes: Coverity CID 135216
