iio: add __counted_by_ptr attribute to channels in struct iio_dev

In 'struct iio_dev', the 'channels' pointer refers to an array of IIO
channel specifications ('struct iio_chan_spec const'), and the size of
this array is tracked by the 'num_channels' field within the same
struct.

Applying the '__counted_by_ptr' attribute to 'channels' allows KASAN
and compiler-based bounds checkers to verify that accesses to 'channels'
remain within bounds at runtime.
