iio: adc: stm32-adc: fix stopping dma
There maybe a race when using dmaengine_terminate_all(). The predisable
routine may call iio_triggered_buffer_predisable() prior to a pending DMA
callback.
Adopt dmaengine_terminate_sync() to ensure there's no pending DMA request
before calling iio_triggered_buffer_predisable().
Fixes: 2763ea0585c9 ("iio: adc: stm32: add optional dma support")
