mt76: sdio: disable interrupt in mt76s_sdio_irq

It is unnecessary to keep the interrupt enabled in mt76s_sdio_irq because
the driver is already aware of the interrupt, schedules the
mt76s_txrx_worker to handle the corresponding actions, and eventually,
the interrupt would be enabled again when mt76s_txrx_worker finishes its
work.

So we can safely disable the interrupt in mt76s_sdio_irq as soon as
possible to increase the CPU productivity by dropping the redundant
interrupt triggers.

Note that sdio lock acquired/released would be handled in sdio_irq_work
at mmc driver so we don't take care in mt76s_sdio_irq at function driver.
