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]
