Bluetooth: btmtksdio: Do close if SDIO card removed without close

Browse Source 
commit 0b6d58bc6ea85e57de25c828444928e4a0aa79cb upstream.

To prevent Bluetooth SDIO card from be physically removed suddenly,
driver needs to ensure btmtksdio_close is called before
btmtksdio_remove to disable interrupts and txrx workqueue.

Fixes: 6ac4233afb9a ("Bluetooth: btmtksdio: Prevent enabling interrupts after IRQ handler removal")
