drm/vgem: add missing mutex_destroy
[ Upstream commit 7c18189b14b33c1fbf76480b1bd217877c086e67 ]
vgem_fence_open() instantiates a mutex for a particular fence
instance, but never destroys it by calling mutex_destroy() in
vgem_fence_close().
So, add the missing mutex_destroy() to guarantee proper resource
destruction.
