miniport: halve QXL_IO_UPDATE_IRQ calls
QXL_IO_UPDATE_IRQ causes the device to check int_mask and int_pending
and issue an interrupt if that is required. Since we just zeroed
int_mask, no interrupt will ever be issued. Since we issue another
QXL_IO_UPDATE_IRQ in the interrupt routine DPC right after resetting
int_mask any pending interrupt will be raised then.
