[ Upstream commit 6ac4233afb ]
Ensure interrupts are not re-enabled when the IRQ handler has already been
removed. This prevents unexpected IRQ handler execution due to stale or
unhandled interrupts.
Modify btmtksdio_txrx_work to check if bdev->func->irq_handler exists
before calling sdio_writel to enable interrupts.
