libmsc/gsm_04_11.c: properly handle MMTS indication
According to 3GPP TS 29.002, section 7.6.8.7, MMS (More Messages to Send)
is an optional IE of MT-ForwardSM-Req message which is used by SMSC to
indicate that there are more (multi-part) MT SMS messages to be sent.
The MSC needs to use this indication in order to decide whether to
keep the RAN connection with a given subscriber open.
