Fix SACCH channel release indication not sent to BSC after location update.
Based on GSM 04.08 3.4.13 RR connection release procedure, after the network
sends a deactivate SACCH it receives DISC from MS which cause BTS to
send RLL release indication to BSC in order to stop T3109 timer. It has been
found that after a location update BSC never receives RLL release indication
which causes a T3109 timeout because no TCH is currently allocated. This fix
ensures RLL release indication to be sent to BSC when no TCH is allocated
in the particular case of a location update.
