bsc: fix sccplite test fallout: deactivate as_Media in f_ho_into_this_bsc()

Deactivate as_Media() once the handover is completed, so that it does
not fail on the expected MGCP DLCX from release.

Fix fallout seen in these tests:
SCCPlite
 BSC_Tests.TC_ho_into_this_bsc
 BSC_Tests.TC_ho_into_this_bsc_a5_0
 BSC_Tests.TC_ho_into_this_bsc_a5_1
 BSC_Tests.TC_ho_into_this_bsc_a5_3
 BSC_Tests.TC_ho_into_this_bsc_a5_4
 BSC_Tests.TC_ho_into_this_bsc_a5_1_3_no_chosen_enc_alg
 BSC_Tests.TC_ho_into_this_bsc_a5_1_3
 BSC_Tests.TC_srvcc_eutran_to_geran
 BSC_Tests.TC_srvcc_eutran_to_geran_a5_3
 BSC_Tests.TC_srvcc_eutran_to_geran_src_sai
 BSC_Tests.TC_srvcc_eutran_to_geran_forbid_fast_return
 BSC_Tests.TC_ho_into_this_bsc_sccp_cr_without_bssap

All of these tests use f_ho_into_this_bsc().

(It is not clear to me why only the SCCPlite tests show the fallout, the
AoIP should be similarly affected, but isn't.)

The failures were introduced by recent merge of
I0633f60f09d58802f6be0238ef41a632d93a4327, which made as_Media()
stricter by failing on early DLCX.
