Since masklength is marked as [INTERN], no drivers should assign it and
the value will always be 0. Therefore, the local ml accumulator variable
in iio_buffers_alloc_sysfs_and_mask() will always start out as 0.

This changes the code to explicitly set ml to 0 to make it clear that
drivers should not be trying to override the masklength field.
