GTPv2_Emulation: make sure g_uecups_conn_id is populated.

In function f_init, we activate altstep as_uecups_ind at the end of the
function. In as_uecups we use the template generator function
tr_UECUPS_RecvFrom_R(). In this function we use g_uecups_conn_id, which
is only populated when use_gtpu_daemon is set to true. When
use_gtpu_daemon is false g_uecups_conn_id will be <unbound>, which leads
into an error.
