restore sending of optional MM info messages
Since commit 2483f1b050496eda7f8707327204251c57212906 the function
gsm48_tx_mm_info() was not called anymore. No MM info messages were
transmitted to phones even if MM info messages were enabled via VTY.
With this commit, we call gsm48_tx_mm_info() after successfully
processing an IMSI ATTACH location update.
