mgmt-tester: Add a regression test hitting hci_sync bug Add a test "Add + Remove Device Nowait - Success" that hits a race condition in kernel hci_sync.c. On current kernels this causes BUG: KASAN: slab-use-after-free in hci_update_passive_scan_sync+0x857/0x1230 due to unsafe iteration of hdev->pend_le_conns (in Linux <= 6.4-rc4). This seems to hit the race condition also without the added emulator delay (since the emulator runs in the same thread), but it's better to add the delay since otherwise it'll depend on timings on kernel side.
