platform/x86/intel/ifs: Annotate work queue on stack so object debug does not complain
commit 3279decb2c3c8d58cb0b70ed5235c480735a36ee upstream.
Object Debug results in the following warning while attempting to load
ifs firmware:
[ 220.007422] ODEBUG: object 000000003bf952db is on stack 00000000e843994b, but NOT annotated.

Correct this by calling INIT_WORK_ONSTACK instead of INIT_WORK.
