iio: Drop duplicate forward declaration

Commit 5f420b42079c ("staging:iio: Add extended IIO channel info") added
a forward declaration for struct iio_dev to <linux/iio/iio.h> but forgot
to remove an existing forward declaration further down originating from
commit 7ae8cf627558 ("staging: iio: chrdev.h rationalization").
