6.6-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 1e2e3044c1bc64a64aa0eaf7c17f7832c26c9775 ]
Device flags could be updated in the meantime while MGMT_OP_ADD_DEVICE is pending on hci_update_passive_scan_sync so instead of setting the current_flags as cmd->user_data just do a lookup using hci_conn_params_lookup and use the latest stored flags.
