drm/i915: Reject unknown syncobj flags
We have to reject unknown flags for uAPI considerations, and also
because the curent implementation limits their i915 storage space
to two bits.
v2: (Chris Wilson)
* Fix fail in ABI check.
* Added unknown flags and BUILD_BUG_ON.
v3:
* Use ARCH_KMALLOC_MINALIGN instead of alignof. (Chris Wilson)
