always directly send BSSMAP Clear Request

When a gscon wants to send a BSSMAP Clear Request, it makes no sense to do it
conditionally depending on the current conn state. Just send it: don't call
gscon_sigtran_send(), directly go for osmo_bsc_sigtran_send().

In particular, if an incoming inter-BSC handover ends in failure, the gscon
state is still ST_INIT, but if the MSC fails to give us a Clear Command, we may
want to ask with a BSSMAP Clear Request.
