Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work
In btsdio_probe, &data->work was bound with btsdio_work.In
btsdio_send_frame, it was started by schedule_work.
If we call btsdio_remove with an unfinished job, there may
be a race condition and cause UAF bug on hdev.
Fixes: ddbaf13e3609 ("[Bluetooth] Add generic driver for Bluetooth SDIO devices")
