Subject: [PATCH iwl-next v1] idpf: refactor some missing field get/prep conversions

Most of idpf correctly uses FIELD_GET and FIELD_PREP, but a couple spots
were missed so fix those.

This conversion was automated via a coccinelle script as posted with the
previous series.

Signed-off-by: Jesse Brandeburg <jesse.brandeburg@...el.com>
---
This patch should be applied after the larger FIELD_PREP/FIELD_GET
conversion series for the Intel drivers.
