Bluetooth: btmtk: Fix failed to send func ctrl for MediaTek devices.
[ Upstream commit 67dba2c28fe0af7e25ea1aeade677162ed05310a ]
Use usb_autopm_get_interface() and usb_autopm_put_interface()
in btmtk_usb_shutdown(), it could send func ctrl after enabling
autosuspend.
Bluetooth: btmtk_usb_hci_wmt_sync() hci0: Execution of wmt command
timed out
Bluetooth: btmtk_usb_shutdown() hci0: Failed to send wmt func ctrl
(-110)
Fixes: 5c5e8c52e3ca ("Bluetooth: btmtk: move btusb_mtk_[setup, shutdown] to btmtk.c")
