iio: adc: exynos_adc: Replace indio_dev->mlock with own device lock

Browse source

As part of the general cleanup of indio_dev->mlock, this change replaces
it with a local lock, to protect potential concurrent access to the
completion callback during a conversion.

This is part of a bigger cleanup.
