Bluetooth: btmtksdio: mask out interrupt status
Currently, there is a loop in btmtksdio_txrx_work() which iteratively
executes until the variable int_status is zero.
But the variable int_status should be masked out with the actual interrupt
sources (MTK_REG_CHISR bit 0-15) before we check the loop condition.
Otherwise, RX_PKT_LEN (MTK_REG_CHISR bit 16-31) which is read-only and
unclearable would cause the loop to get stuck on some chipsets like
MT7663s.
