Subject: platform/x86/intel/ifs: Annotate work queue on stack so object debug does not complain

From: David Arcari <darcari@xxxxxxxxxx>

commit 3279decb2c3c8d58cb0b70ed5235c480735a36ee upstream.

Object Debug results in the following warning while attempting to load
ifs firmware:

Correct this by calling INIT_WORK_ONSTACK instead of INIT_WORK.
