iio: Use kmalloc_array() in iio_scan_mask_set()
A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
