tests/msc_vlr: fix: do not pass RAT type to expect_bssap_clear()

The function name implies OSMO_RAT_GERAN_A, and it has nothing
to do with other OSMO_RAT_* types. Found using clang:

  warning: too many arguments in call to 'expect_bssap_clear'
           expect_bssap_clear(OSMO_RAT_GERAN_A);
	                      ^^^^^^^^^^^^^^^^
