sgsn: Call mm_ctx_cleanup_free to deregister MM context

Currently the MM context isn't always removed when it is
de-registered (mmctx_timer_cb), mm_state is set to GMM_DEREGISTERED
instead. This can lead to left-over MM contexts which are only
cleaned up if the MS reattaches.

This patch replaces all of these assignments by a call to
mm_ctx_cleanup_free.
