[PATCH v2 27/27] iio: Drop iio_device_claim_direct_scoped() and related infrastructure

[Jonathan Cameron <jic23@kernel.org>]

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

Scoped conditional automated cleanup turned out to be harder to work
with than expected. Despite several attempts to find a better solution
non have surfaced. As such rip it out of the IIO code.
