iio: inkern: allocate zeroed memory
Use kzalloc() rather than kmalloc() for initializing the iio_channel structure.
This patch enables the iio_dev and iio_chan_spec are set to NULL.
This may prevent the page fault problem because the pointer of iio_chan_spec
is initialized as NULL.
The iio_chan_spec is updated only in case that the IIO map has
specific channel label.
When the map has no ADC channel label, then the value of iio_chan_spec
remains as invalid pointer.
To prevent this problem, the pointer should be initialized as NULL.
