[PATCH 10/12] iio:dummy: Drop set but unused variable len.

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Not sure what the thinking was here, as lost to history, but the
variable is clearly not used so get rid of it.

Warning seen with clang W=1 tests (may be present with other compilers
and build options).
