[Ashutosh Dixit <ashutosh.dixit@intel.com>]

An OA property value of 0 is invalid and will cause a NPD.

Reported-by: Peter Senna Tschudin <peter.senna@linux.intel.com>
Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/6452
Fixes: cc4e6994d5a2 ("drm/xe/oa: Move functions up so they can be reused for config ioctl")
