adapter: wait for kernel exp features in adapter initialization Things like BAP depend on ISO sockets being enabled in kernel. It is possible the MGMT commands enabling experimental kernel features do not complete, before BAP etc. initialization and probing starts, in which case BAP will be mostly nonfunctional. This was observed to occur always when running BlueZ in a Fedora VM, requiring bluetoothd restart after every boot for BAP to work, log containing lines in the order: bluetoothd[981]: src/adapter.c:read_exp_features_complete() 6fbaf188-05e0-496a-9885-d6ddfdb4e03e flags 0 action 1 bluetoothd[981]: src/adapter.c:read_info_complete() index 0 status 0x00 bluetoothd[981]: profiles/audio/bap.c:bap_probe() BAP requires ISO Socket which is not enabled bluetoothd[981]: src/adapter.c:iso_socket_complete() ISO Socket successfully set Fix by waiting in adapter initialization that all MGMT exp feature requests are done, before proceeding to read adapter information. Also fix canceling MGMT_OP_SET_EXP_FEATURE for ISO sockets.
