drm/syncobj: Fix memory leak in drm_syncobj_find_fence()

Commit 18226ba52159 ("drm/syncobj: reject invalid flags in drm_syncobj_find_fence") forgot to take into account the fact that drm_syncobj_find() takes a reference to syncobj and returns early without dropping the reference, leading to memory leaks.
