bsc: f_expect_dlcx_conns(): do not rx Clear Complete

The function f_expect_dlcx_conns() is clearly related to MGCP, and
semantically should not interfere with BSSAP by also receiving the Clear
Complete.

For some tests, this incidentally makes sense, but an upcoming test
failed in a non-obvious way because of this.
