[ Upstream commit a76a0d365077711594ce200a9553ed6d1ff40276 ]

Current code is actually failing on the following tests of mgmt-tester
because get_adv_instance_scan_rsp_len did not account for flags that
cause scan response data to be included resulting in non-scannable
instance when in fact it should be scannable.
