drm/xe: Fix warning on impossible condition
Having a different value for op is not possible: this is already kept
out of user-visible warning by the check in xe_wait_user_fence_ioctl()
if op > MAX_OP. The warning is useful as if this switch() is not update
when a new op is added, it should be triggered.
Fix warning as reported by 0-DAY CI Kernel:
drivers/gpu/drm/xe/xe_wait_user_fence.c:46:2: warning: variable 'passed' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]
Closes: https://lore.kernel.org/oe-kbuild-all/202312170357.KPSinwPs-lkp@intel.com/
Fixes: dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs")
