Subject: [PATCH] Bluetooth: mgmt: Fix wrong param be used

From: Clancy Shang <clancy.shang@...ctel.com>

if the BlueZ library calls the API interface "adapter_set_device_flags",
which sends the "MGMT_OP_SET_DEVICE_FLAGS" opcode to the kernel, but
does not receive the callback message "MGMT_EV_DEVICE_FLAGS_CHANGED"
from the kernel. it fixs this bug.
